2006 BMW 3 Series Sedan 325i 4dr Sedan (3.0L 6cyl 6M)
So far, so good
 I bought a CPO 325i (my first "luxury car") with sport and premium packages and about 36K miles in December 2009, as it was coming off of lease and still under factory warranty/maintenance.  So far, so good, although I have had several incidents with the rear passenger window staying down until the engine is turned off and re-started - I took it into the dealership and it worked perfectly so there was no way they could diagnose the problem.  Anyway, the 325i sport handles very well, and has a very solid "feel."  However, when I replace these tires, I will use standard rather than run flat tires as I am convinced the ride will be much smoother, even with the sport suspension.
