2001 BMW 3 Series 330i Rwd 4dr Sedan (3.0L 6cyl 5M)
For the first 3 years I owned the car, I only needed to change the oil and some minor maintenance, but in Feb of 2007, it was a chilly -20 degrees Fahrenheit and the crankcase vent froze up and it hasn't been the same sense. In fact, it happened again in Jan 2008. I was able to have it brought to BMW who graciously covered $3800 of the $4000 repair bill. Since then, I have had an oil sensor replaced, dipstick brake off and now my rear suspension coil needs to be replaced (not sure how that could have broken). My next car will be a Honda or Nissan..
Handling is incredible, a great car to drive on curves and it is fast from a stop and stops on a dime
BMW's cold weather testing facility in Sweden may need to moved to Canada or Minnesota. It gets much colder here.
