Was around a bunch of Audi's this weekend. Wow, has the S6 really improved in style, can't say about the performance but the numbers look good. Of course Premium Package S6 will run you $85k, but damn it looks good. The S6 from 2013 or so is not nearly as stout and aggressive looking as the new ones, impressive. The RS5, TTRS, RS7, A6 TDI, V10 R8, and others seem ok too...I'll dig up some pics. Check out an 2015 S6 in person if you can, makes our poor beast look a bit outdated.
Edit; Might be the 2016 Model it looks like by the listings, but around $80k. The 2014 just doesn't seem to have as much style or strength. I swear the new one is a bigger car, bit longer than the RS6.
Not getting a new car anytime soon, but I've been thinking of waiting 5-6 years for a used RS7, just can't get over how bad/bland the rear end looks on them.
Edit2; Pics...RS7 turbos on top, nice!
