I just read this topic and an interesting comparison given I was thinking through the same exact comparison for the past two months. This is what I decided on. I had a 2014 Jeep SRT that I loved but always wanted to get back to a sports sedan. I mean, our Jeeps are fast but they can't really corner like a true sports sedan. I had mine supercharged with the RIPP 2 kit. No problems with it ever. Immaculate condition with 34k miles, Max Steel color. It's for sale right now at the Toy Barn in Dublin, OH for $56k. I got a little over $50k for it in trade. I think a fair deal with the supercharger upgrades I put into it.
I was also looking at the RS7s but they were always a little out of my price range. I ended up trading it for an immaculate Audi S6. 2014, Prestige package with B&O sound system, already APR tuned, AWE touring exhaust, lowered, tinted and built in custom K40 radar with laser Jammers. A great buy at around $53k. The reason I think the S6 is a better buy than the RS7 is that for about $10k, I can upgrade the turbos, coolant and downpipes and have an S6 as fast as a stage 1 RS7 or RS6. The main difference between the two are the turbos and tuning. It's already an AMAZING car and incredibly fast with the APR stage 1 ECU&TCU tune, runs quarter mile in mid 11 seconds and 0-60 mid 3 seconds.
Here's picture of my Jeep I traded:
Here's pictures of my new to me S6. I maybe back to the Jeep, when the Hellcat comes out but for now, I'm going to have fun with this.
