I'm looking at buying a certified pre-owned S6, and I'm curious to hear what y'all think about previous models. I've been looking at 2013 and 2014 models the most. The 2013 models are more in my price range, but I've seen a few 2014 models that are reasonably priced.

What are generally considered the better models from 2014-back? And even though this is an Audi forum, are there any other great pre-owned sports cars (or luxury cars with good performance) in the $50-60k range that y'all recommend? I've looked at a few pre-owned Porsche Cayenne GTS rides as well, but I think I'd prefer a midsize car that's fun to drive but the ride isn't too harsh for an everyday car.

Thanks in advance!
