I have owned several different RRS and RRS-SC products and love the vehicle. I am contemplating switching to something slightly larger to accomodate our lifestyle a bit better and am considering a full size '12 RR (NOT SC) with all the options except RES. I am curious to know other opinions on the vehicle and if anyone else made the change. The first few things I noticed is there aren't any passive keyless options for the full size which all of our vehicles in from our recent past have had this feature which is a small thing to look over but I am more concerned with the vehicle size, weight and engine pairing. Is the N/A motor sufficient for such a large vehicle or does the vehicle feel like it definitely needs the SC option to get it going on the highway?
