I bought mine in 2008 with 28K miles.
I sold my 2003 325i to get this car. Just like the 3 series, I LOVE the way this car drives. The power, acceleration and steering are incredible. It's super smooth at high speeds - you just don't know you're speeding! After about 50K miles I was experiencing jerkiness in the transmission. Sometimes at a stop the engine would race and I'd have to shove my foot on the brake. I mentioned it several times to my dealer and finally, at 99K miles (I had the extended warranty) I asked to have a mechanic ride with me and I got a new transmission :) Cupholders suck; don't like the iDrive and interior is so-so, but I still like the car!
Owned my 2005 530i for 3 years and never had one problem with it. Drove like a dream and always loved driving it. I put on about 12,000 a year mostly city driving and it performed great. A little tight up front (I'm 6'3) but overall the space inside is good. The interior design is very good the bluetooth always worked great with my phone and IDrive didn't bother me once I got used to it. The cup holders are ok they're not to bad never had a problem with them. The car is also very safe I got into an accident and the car held up great. Just recently sold it with 57,000 miles I upgraded to a 2008 535xi I hope I have the same luck with it !
Handling, gas mileage, performance, exterior design, xenon lights + halos
Better traction in rain, seats that go back further, better quality plastics (all was addressed in 08+ models)
I had 3 cars sitting in my garage, one was a BMW 545i (2005) one is a GMC Envoy (2002) and the other is a Toyota Tacoma Truck (1996)
The BMW continued to leak oil all over the garage until I finally sold it.
The Envoy and the Tacoma have about 200,000 miles each and I doubt that I have even spent $500 combined on the 2 of these cars since I have owned them.
The BMW has been nothing but problems with every maintenance bill being at least $1,000.
Just a battery alone for the car is almost $500!
The car was the best driving car I have ever owned but reliability was the worst of any of the 20 cars I have owned since I first started driving.
I traded it recently for a Toyota!
In all, the 545i is a well-balanced rig -- amazingly fast and agile for a car of its size and comfort.
My car has been plagued with electrical issues however, and a glitch with the transmission is enough to force me to replace it.
When driving under slight power between 35 and 40 mph, the car feels as if there is a disruption in the fuel delivery or ignition.
When I first demonstrated this to the dealer, a tech said it was the transmission, it was normal, and by shifting it to sport mode I could eliminate the issue.
Unacceptable, in my opinion.
This isn't "normal" behavior for any car, and I don't want to drive in sport mode to fix a transmission malfunction.
Major buzz kill.
Power and handling; styling (though not for everyone); instrument cluster; nav system.
idrive -- clunky
and sometimes slow to respond; automatic transmission, which disrupts the power delivery between 35 and 40 mph; seats are too hard and slippery; closing the trunk lid requires coordination and heft; exhaust note is akin to a Chevy Malibu; iPod connection is cumbersome (located in the glove box).
Great car but there is a issue with the CCC aka iDrive. I had one go out under warranty at about 40,000 and now again it went out at 79,000 but this time I have to pay and it costs $1600 to replace. I have the certified pre- owned warranty which the dealership that I bought from said was bumper to bumper (the salesman lied) and now I have to suffer the consequences. Also the brakes squeal even though they do not need to be replaced. The rear tires wear fast because in the sports suspension, the wheels are slightly inward on purpose for handling so you will have to change tires frequently. Do not recommend if you don't have a lot of money to pay for service.
