I'm looking at a 2006 Sport model, with 118k miles and am a real novice at these vehicles. Can someone please advise me what specific issues I should be looking out for?? I know RR has a bit of a reliability issue over the years. The car looks outwardly very nice and has a clean CARFAX report, and single owner. I'd like to have a knowledgeable mechanic check it out generally, and specifically for any known problems that these vehicles tend to suffer from. Thanks for your input, in advance!
