2005 BMW 3 Series 325i Rwd 4dr Sedan (2.5L 6cyl 5M)
My wife bought a used '05 325i in mid '09 with 80k miles. There were a few minor things the car needed and I am a former mechanic, so I had checked the car over well enough to know it wasn't in terrible shape. The issues were minimal at first but then the list started and hasn't stopped. We have put 60k miles on this 9 year old car and have done the following; various plastic clips/parts all over the car, windshield washer pump, coolant hoses and expansion tank, oil filter housing gasket, front control arm bushings, belt tensioners and idlers, A/C evaporator core, transmission service, two window regulators, fuel pump & filter, etc. I could go on but I'm out of space. Plan on spending a lot.
Nice short trip road car, not so great for longer distances. The ride is stiff and so are the seats. Handles very well, drives like a dream but the cost of ownership is pretty high. Very reliable engine but don't neglect the cooling system. Overall, a decent car but not what I expected.
Where to start? Too much use of plastic in some critical places - coolant fittings and elbows, water pump pulley!, etc. The car sold for over $35K in late '04, one would expect some repairs but this has been excessive in my opinion. I've owned other German, Japanese, and American vehicles but I think this one may have been the costliest to keep going, and I am doing 95% of the work myself...
