How many miles did yours have? I got my 2017 RS sedan for 17k with 4 miles. Mine also doesn't have the leather interior, which kinda bums me out. I plan on getting it reupholstered anyway though. Welcome!
Let me know how your deadening goes! I am considering the same with my 2014 hatch. It's much quieter than my previous car was, but I would like even more, and I still have a roll of soundskins left over, so I am certainly doing the hatch at the least.
Just picked up new 2017 RS for $15500 . Wish I was able to get the the leather seats in the premium but no incentives for the premium. I'm about to take all the interior out for a head to toe sound deadening job. Should be fun.
