*I bought a used 2005 645ci after owning a 2009 vw passat and it came with after market parts like wider back wheels and carbon fiber hood and it has enabled the car to achieve a quarter mile of 12 seconds. *If you get an exhaust delete for this or after market exhaust the car will sound like thunder ,it catch alot of people by suprise it cracks me up. *I gapped a dodge durango srt and i kept up with a 2011 bmw m5 with this model bmw so far.Warning it can become very addicting to drive this car like youll end up blindingly spending hundreds of dollars in gas a week just because of the adrenaline rush you get from pulling off from slower cars and knowing youll always win. *Next thing if you bought this car at 190,000 miles on dash you better start saving to $12000 because after 1600 more miles your gonna get a transmission failure error on your screen and your car wont be able to go in reverse and your gonna need new trans. *Leaks oil after 100k miles

Awesome Coupe

What an excellent ride! This is my 3rd BMW and I most recently has a Lexus GS430 which was not fun to drive at all.The 645 CI has great power and it just keeps going faster and faster. Fuel economy is much better than I expected. I average 19-20 miles between city and freeway driving. Learned the whole iDrive system in a week. This is a good way to keep the dash clean.

What Fun

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.

Almost Perfect

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.

WONDERFULLY LUXURIOUS FUN TO DRIVE

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.

No Sports Car, But Great Tourer

Fantastic acceleration and stopping power. Pretty slushy in normal mode, but the "sport" button makes it very responsive. Active suspension is incredible. iDrive is a great alternative to dozens of tiny buttons, and is surprisingly intuitive, as is the voice command system. Very quiet and solid-feeling. Turns heads. Main criticism is that the driver is quite isolated from the road. Interior a bit disappointing for a car in this price bracket (lots of plastic, cheap carpet).

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.

Since 1992 the only car me and my wife ever drove was the 7 series, there never was another car for us, but got tired of waiting for the new on order 750, decided to try something new. WOW!

I cannot tell you how much I have enjoyed and am still enjoying this car after almost 1 year. I have had every type of car you can think of. However each car gets "stale" after a while. This car is sooo different I enjoy driving this car everytime. I live in Florida in the winter and New York the rest of the year. Driving either on Florida Highways or the Streets of New York, this car is amazing.

The tiptronic takes a bit of getting used to. It is very different and you should be very familiar with it before ordering this option. If you get a 04, it will not have bluetooth, and it will cost you over 2500 to get it retrofitted. The phone that comes with the car is junk, and neither BMW nor Cell companies will take any responsibility of hook it up. The microphones for the phones are junk. There are two possible upgrades that they will only tell you about after you complain loudly that people cannot understand you when calling from your car. I still only know about 100 of the 500 functions the I drive is able to perform. The dealership also does not know how it operates, figure it out!

My brother Tom bought this car, gave it to me and it is UNBELIEVABLE. Having previously owned a 7 series, two 3 series, and even a 2002 TII (wow), these guys never fail to amaze me. This ride is extremely smooth, responsive and agile. Now, I gotta go get one myself!

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.

I am loving this car more and more every day. The sound system is amazing, the handling at high speed on corners and curves is the perfect adrenaline rush, and yet the ultimate in safety. The leather seats conform to your body and contrary to the editor's remarks, this car is very sexy and its lines grab all the attention on the road. Even from those "elite"...not mercedes benz owners ( since the editor is so bias to those old-man vehicles). thank you. The next thing for me will be the M6.

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...

I love it. I love BMWs, compared to my old M3, this car absolutely is amazing and i highly recommend it for anyone looking for a new car. One downside, the back seat could use more headroom and space. The 3 series probably has more than the 6, which is weird. Overall though, the car rocks.
