Like the S4, the A4 has a lot of details going for it. You get the upmarket styling that has made Audi models from this generation memorable. The performance of the A4 is also quite impressive, and there was a limited edition model with a V8. The car still looks and drives great today, and there are plenty of them around (via Car Gurus).
The A4 is one of the most desirable used luxury cars you can get. When you get behind the wheel of an A4, you will feel successful. From the luxury appointed interior to all the standard features that the car came with. Plus, you get the prestige of driving one of the best-designed cars in the world.
