8: Audi A4
Building on the same successful formula of the S4, the A4 is an equally fun-to-drive Audi. The engineering is top of the line and the car had a completely revised exterior. The reliability of the S4 has gotten high marks from previous owners and the automotive press., which means buying a used one is a great investment (via Car Gurus).
But when it comes to the Audi A4, the most important thing is the performance, and the A4 delivers in spades. The car is one of the most notable Audi models to take on the recent design changes. The engine is one of the best, and the engineering gives the car a top-notch feeling even for a used model.
