2008 BMW 5 Series Sedan 535i 4dr Sedan (3.0L 6cyl Turbo 6M)
Fun to drive, poor reliability & expensive to fix
 This was my 1st and last BMW. Bought the car new, in the 6 years and 34K miles I've owned the car, I had afaulty battery, bad fuel pump, dead oxygen sensor, and a failed water pump.I was stranded 3 times (car completely died) and almost stranded twice. So, multiple trips to the shops and over 2 grand of repair bills later, I have finally gave up on this "ultimate driving machine". It was a fun car to drive while it worked. But, for a $60K car, I'd expect BMW to deliver something better. The worst part is that I totally lost my confidence in it and can no longer feel comfortable taking this car on any extended trips. This will be the LAST BMW I ever spend my money on.
