Currently looking at a red RRS SC v8 with 74k miles and comes with 100k mile/2 yr power train warranty. Got him talked down to $30k. Decent deal? I noticed that the silver lettering was starting to look dark gray. Is that something the silver accents do? Also, on several RRs I looked at, there seems to be some wrinkling/bubbling on the roof near the doors. Looks like tape residue or something but I'm wondering if it's maybe the adhesive showing through from the underside of the roof piece?
