 I got my 2003 6i with 33K on it fresh off a 3 year lease.  I have had only 1 problem in the last 35K miles and that was a noisy drive belt idler.  I replaced that and have not had any other issues.  The car is easy to work on and easy to own.  The only heartburn I have with the car is the turning radius, it's awful.  Other than that I love it.  30MPG combined hwy and city.
