My wife and I feel in love with our 05' BMW 645i conv. when we first picked it up. We purchased it Jan. 2011 used with only 33,000 miles on it. It had some years on it but we figured it would get several years of only normal maintenance type services and not need to worry about major mechanical or electric problem because of it's low mileage and series. After all this is one of BMW's flagship cars. While the car gets looks of admiration at stop lights the feeling of this wears out quickly when you count how many dollars and time it has spent in a BMW repair shop. The BMW 645i is like buying a boat - the 2 happiest days of ownership are the day you buy it and the day you get rid of it.

Owned a 308, a 365, two Aston Martins, a slab sided Cobra, more MBZs than I can forget and I have to say this is the finest all around automobile I have ever owned. The car is dependable, forgiving and a joy to drive hard and fast. Spent 14k at 90,000 to replace items that had not yet failed but what does it matter since my old chum has never let me down. Am now at 203,000 miles and all is still well.

The car is wonderful when youre just cruising, it makes a little purr but when you put it in the sport mode and accelerates, its extremely loud. When the roof is up it doesnt make too much noise. And with the roof down it doesn't make those annoying noises that other cabriolets make. The interior is very elegant with its ambient lighting.

Driving this BMW is a great experience each time I start the engine, except for the iPod screen warning that comes up everytime. I treat it like an annoying child, and try not to pay attention to it. Finally, though I have to acknowledge it to work the radio, ect. Oh well, small price to pay I guess, for a great car. I was surprised the visibility in the convertible with the top up was excellent. This is really a 2 person car, with room for 2 small children.
Wonderful car but too many problems!

We loved everything about our 2005 645I convertible. Talk about a car that catchs everyone's eye and is a blast to drive! But....we had so many problems with ours we regretfully ended up giving it back under the lemon law. It was in the BMW service dept 32 days between July 6 and Oct 1, 2006 - not counting weekends! We were told it had 19 computers by 15 manufacturers and the glitchs weren't worked out yet. We expected more from an $80,000 car but agree we'd buy another one if we were promised it wouldn't have so many problems!

Drove 3-series all my life until I got this beast. 6 speed is out of this world. Acceleration, handling and cornering couldn't be finer. I swapped out the run flats immediately even though there was only 19,000 on car. What a difference without that extra weight. Less expensive too. First gear buries the tach a little too fast but you get use to the quick shift to second. I took it to the limit 160+ once and it was still quiet in the rag top. The iDrive is simple once you read the manual. Quality and variations of the LOGIC7 is theater- like. I'm 6'7" and the cockpit is very accommodating. I just love my BEAST for power and style.

Reliability is an issue - right now I need to take the car to the shop to get the engine gaskets replaced, the intermittent PDC failure analyzed, the trunk lock sensor fixed so that I can open it with the remote, the brake fluid flushed, the interior filter replaced, brake pads replaced, etc.

I had read all of the review and was a bit reluctant, until I drove this vehicle. For a vehicle of this size, it handles and corners amazingly well. Performance is outstanding! 0- 30 is strong; however, 30-100 is absolutely incredible and leaves most everyting in the dust. To top it off the ride is compliant, the seats are the most comfortable I have ever encountered, the logic 7 sound system is amazing - even at super legal speeds with the top down. The much maligned I Drive in now very intuitive - once you read the manual just once. This is the best car I have ever owned or driven! It you are looking for a great convertible - at any price - this is it!
I Love this Car!

Just purchased my 645ci May 05 and what a spectacular ride. Turns on a dime. Smooth. Lots of power. Great touring vehicle. This is my third BMW and I rate the BMW as the best to own. Surpasses any other auto I've owned and driven. Can't beat the service and care they give to the customer not to mention the vehicle. I highly recommend this car if you want something practical but sporty. People give second and third looks when you're driving this dream machine. I wouldn't consider another maker. I've been sold on BMW for years. Still have first original/first BMW (525i) When our last child starts driving the Mini Cooper is at the top of the list of consider- ations. Thanks BMW!

This car is very reliable, but servicing this vehicle can be pricey. Make sure you go to a shop that is very familiar with BMW vehicles. This is a nice luxury vehicle that likes to show off its interior. Smooth comfortable ride. Performance and handling is what you would expect from BMW. Not sure I would want this as my only car but it is a nice addition to the SUV.

Just bought this car this past august. I've seriously have driven the car no more than two weeks. This car is already a nightmare. Gasket leaks and misfiring issues. Should have stuck with Mercedes. BMW dealer can't even pin point the issue. Very poor customer service. BMW of Peabody ma. Stinks. I'm ready to throw in the towel at this point.

Having owned several sports cars such as the 92 Acura NSX, 97 Porsche 993 C2S (911), and 03 Boxster S, I was blown away and extremely impressed with the overall package BMW delivers with its legendary 6 series. Absolutely amazing piece of engineering. I was impressed enough to opt out of another Porsche purchase. Granted it isnt a Porsche Cab or Carrera, albeit that's probably a good thing. Tight handling, absolutely sexier when you have the top down, and the more I look at this car, the more I lust after it. Great value too. Makes a nice sister to our 2005 745i. Gorgeous, elegant, sleek, and fast.

I think you can have a much better car for the same money. My car has been giving me a lot of headache with the operation of the roof; it stops working without previous notice and not even the BMW guys know why is that. She still is covered by the warranty but my concern is when it's over I'll be the one paying every time this happens again. Other than that, she runs ok but the engine isn't that amazing considering it's a V8 (should have much more grunts and ponies). Anyway, I wouldn't buy it again. Next time, I'll try Mercedes, Porsche or Audi.

You already know you have overdone it with the electronics. I have 1800 miles on this car and it has been in to the dealership 3 times already. I can't wait for the lease to expire so I can buy a Porsche. Thank god I leased this car and do not own it. Get the idea I'm frustrated? All the problems have been computer related.

The 645ci is a driving experience! No of my friends can understand why I would pay this much for a car, I simply tell them that they have to drive it to understand it. Handling is excellent, braking excellent, styling excellent, quality is excellent...It's a real head turner for all age groups and gender!

Moved out of a Benz SL600 into the 645CiC. The BMW has better braking, refined seating and no loss of performance; smoother and a much more quiet ride; Unlike the Benz, the Beemer roof line is not friendly to tall people.

the 645 Ci is the sixth convertable that I've owned starting with a TR-3 and my last car was a MB SL500. The 645 is by far the most fun to drive, and the best to be seen in. I've never had so many people say great things about a car I've been driving, in car washes, at stop lights, parking lots,etc.etc. You get used to the iControl.

Car runs really well. A lot of goodies for the price. iDrive navigation a bit hard to get used too. Fuel economy on open road is good. Fast times off the line. Sattelite radio, HUD , Sport package really complete the total package. Worth the extra bucks. Only feqature lacking is that side mirrors dont fold via power. A bit noisy with top down, at high speeds !!! I traded in Audi A-4 cabrio, big difference!!! Go for it !!
Fast, fun, gorgeous and furious!

My husband bought me this car after I had been eyeing it up on line for months. I could not be happier. I, too, drove a Porcshe 911 Carrera and the 645 makes that car look like a joke! I have never had any problem with taking turns at high speeds and the driving experience is simply that... an experience. The lines on this car are gorgeous and the color combo I chose is just stunning (silver grey metallic with grey top and burgundy interior)! Definitely gets lots of compliments and stares! I absolutely adore this car!

The 645 cic is a fun car to drive. It handles with excellence and attracts the "nice car" symbol with the thumbs up everywhere I go. What I am disappointed with is the malfunction of the I drive system (resetting itself or freezing). My roll bar protection for some reason has deactivated itself. I made an appointment on January 3rd to take my car in and unfortunately the next available date is the 20th of February. Very disappointing for a 90k car.

The 645 is a great car to drive with the top down or up. The acceleration is good for a car of this size and weight, although it could always be faster. Handling with the sport package is good and I drive quite a bit on winding mountain roads and it handles great. I have yet to feel drift or loose traction even at 80+ on S turns. Acceleration on straights could be better. Overall a great touring car (as advertised).

This is a super vehicle.We just purchased the car and have absolutely loved driving it.The power, braking, steering of this car are awesome. It's like riding a high tech roller coaster, smooth and on a rail.The iDrive is cool. It IS very easy to use once you navigate thru it a few times. We got this car w/out the sport package and were told it did not come w/run flat tires.This was not the case, as tires marked with the letters RSC circled are run flats. (No spare tires in this vehicle.) Also, the convertible has more head room in the rear seat than the coupe. I am 6' and 210 & I can sit straight up w/some leg room. Coupe I have to tilt my head.Trunk has more room w/top down,then any other in its class.

This car has it all and then some. Most fun I've ever had driving. It is an experience... it inspires you to really want to take the car for a drive. It's not transportation , it's entertainment and excitement. I never thought a vehicle could motivate you to drive, but this one does. It's a high performing, head turning machine. If it's in your budget get it and you'll not regret it!!!!!!

This car is a rush to drive. You have to take it around a tight corner at high speed to really appreciate the performance. It hugs the road, no lean, even acceleration. A great driving car.The iDrive is a nuisance, and the run flat tires are unnecessary, but overall it is a thrill to own and drive. Spectacular sound system. Have fun!

Sure the iDrive is clunky and the fuel economy is poor. Once you get past those items you'll be in for the fun ride of your life. The convertible is a head-turner, and a neck-snapper. Cool performance, design and engineering makes this a great vehicle. I was looking for a large performance convertible and this Beemer fits the bill.

As a few more of these cars are on the road here in Virginia, I've begun to notice how truly unique and special. I alternate driving this car and an X5 4.8is purchased this spring for practicality. While the responsiveness of the car is thrilling, I wish it had better acceleration. It feels quicker, but I know it's not as fast as my X5, and always makes me wish for more. The handling is fantastic, as is the braking. If I were to change anything, besides the horsepower, it would be the iDrive. While I've mastered it, the touch screen in a previous Lexus and my wife's Sienna are sooo much easier and intuitive to use. Different for the sake of being unique does not excuse this feature.

This car is wonderful, drives like a dream, my two kids fit in the back, great agility, stopping, all the airbags are great and convertible top comes up and down at 20 mph or less. The overall design is wonderful, even down to the cup holder - navigation is superb. The iDrive drove me nuts, had to go to a class to learn it, great now that I understand. The Bluetooth is slow with my Motorola v3 phone and sometimes cuts out. My friend from Germany does much better with the voice commands; it doesn't understand a southern accent very well, and gives me the wrong commands at times. Great car!! Fast and fun and not everyone has one!

Love the car....have a 6 year old in back at all times...it is still ok for space (better than any other Luxury Conver. we drove)...Power, looks, throttle sound all make for an overall wonderful driving car. Best part of the car...with the top down, you get very little if any wind on your face and head. My son in the back get a min. amount too. You can put the top down all year almost with all of the cool/heat features that keep you comfortable. We could not be happier with the car.

When I first learned that BMW was coming back with the six series, I was very interested in seeing the new model. At the time I was ready to purchase my new car, they were then coming out with a convertible and with everything that I wanted on it. I had also considered the 745, but upon seeing the 645 there was no doubt in my mind that that was the car for me. I had a choice of Air Force One or an F- 16. I elected the F-16 and have thoroughly enjoyed driving it. Everywhere I go people compliment me on my stunning car. The car is a dream to drive and have been very happy with it. I highly recommend it.

Everything about this car is beautiful. The lines on the inside and outside were artfully designed. Even the door lights were done in a light blue that are more like mood lights than glarish dome lights. It definitely attracts attention because of it's looks, but it keeps my attention, because it is fun. The convertible top lets the sun in easily, and the press of the gas pedal lets my troubles blow away in the wind.

The looks eventually grew on me and a test drive had me in love with this car. There is nothing like it on the road and it's closest competitor, the CLK500 can't keep up. The M6 with 500bhp will be a higher degree of perfection. Everything about this car shouts fun, style and triple digit speeds.

There is nothing bad about this vehicle, when I bought it, it was great and it hasn't declined in comfort or performance ever since. Buy this vehicle it is a keeper. I would pay up to a million dollars for it. I have a McLaren F1, and this machine is just as nice if not better. A perfect 10.

Although it is hard to write a review on this baby being that I used to drive a Porsche, I will try to be as objective as possible. While it is an eye opener, and it definitely attracts the girls, the handling is at fault. Everytime I turn going anywhere over 20 the tires screech unbearably loud. It does, however, offer luxury that a Carrera just doesn't. Overall, it's a sweet car... a little over priced for what it offers, but hey, it looks nice and drives pretty well.

This is the best car I have ever had. Fun, gorgeous, fits my 6 yr. old in back, he loves it too. Looks like a bullet and drives like one. Head turning looks, throttle sound in engine is very fun. Seats are comfortable, the sound system is great, bluetooth for me works perfectly, very little wind blowing inside the car with the top down, even in the back. Like the window in rear that operates up and down. My first BMW, only MB before, and I have to say, I am not sure what car will come next. This will be hard to surpass all the way around...
