2003 BMW 5 Series Sedan 530i 4dr Sedan (3.0L 6cyl 5M)
They Don't Make Them Like This Anymore
 Purchased from a private party with 25K on the odometer. Currently have about 99.4K miles on it. This has been far the most reliable car we've ever owned - Nissan, Honda, Toyota, Mazda.  When you do basic maintenance yourself, ownership costs are somewhat comparable to many other brands.  Just have to keep an eye out on the cooling system, heard that this was/is the weakest part of the E39's (so far no problems with mine).  Average MPG during summer months: 24-27
