Hello, well this past wednesday my baby A6 4.2 caught fire and i think it is probally totalled. So i have some questions i am looking at a RS6 Ebony Black/ White Interior CF Trim and SE Exhaust. It has 48,000 miles and looks pristine. The one thing i am worried about is that i want a warranty and the car is out of warranty. How much is it to get a warranty on a RS6? Also i have H&R coilovers that i never installed on my 4.2, do they fit on the RS6? Some mods i am also looking into is Giac Chips/Divertervalves/Milltek DP's/ K&N Air Filters. What you guys think? Thanks..........

PS: I am also looking at the B7 RS4 and opinions about that car compared to the RS6
