11: Audi S4
There is just something about a compact Audi model that makes owning one a great experience. The S4 is the epiphany of this with modern Audi engineering and a rev happy motor. Most of these S4 models can be had for a small price, and they offer great features. The engine is one of the most reliable power plants Audi has ever used in a car (via The Truth About Cars).
Even when the car was brand new the styling and performance was lauded by the automotive press. The S4 had a sort of timeless styling that has made the car quite popular in the used market. But its prices have remained steady and you can get a great deal on an S4 and have a car that performs better than you’d expect.
