6. Audi S6
Another high-powered German car on our list is the Audi S6. Audi has a penchant for making fun sports sedans that deliver serious performance. The S6 is one of these standout models. The first thing that we noticed about the S6 is its powerful V10 engine. 435 horsepower will guide you with authority on the freeway and just about everywhere else. The S6 is a stellar deal that has lost a good amount of value since it was new. This is good news for used luxury car buyers who want serious performance that delivers.

We like the S6 for its quality and refinement. The S6 is a big sedan, with a plethora of luxury features that make it a great vehicle. There are other big improvements that the S6 has over the rest of the Audi line, such as a phenomenal passenger area. The backseat on the S6 is huge and remains a big factor to this day. The sheer engineering of the S6 is what has propelled the sedan to such longevity. The smooth-running, powerful V10 engine has a level of quality that you’d only find in a German automobile. If you want a powerful exotic that almost anyone can afford, the Audi S6 is a great choice.
