By now you've noticed a few higher-end luxury sports sedans from across the pond on this list. The B7 Audi S4 is a delight to drive and wringing out the 4.2-liter V8 is a thrill, but as with other high-end offerings on this below-$10,000 list, there are some slight concerns with maintenance costs. In this case, make sure the V8's timing chain has been serviced before going all-in for an inexpensive B7 S4, or you could be facing a repair bill equal to what you paid for the car in the first place.
