I can add this coverage to my policy for $135 per year. Would you do it on a 7 year old S with 45k miles? If I get into an accident it could show up on a Carfax report. For possible resale, I would think a negative Carfax report would out weight the positive of having OEM glass and body panels at that point. So I'm thinking that the only benefit is the personal satisfaction of keeping it OEM. Unless the fit and finish of aftermarket is noticeably different. What's your take on it?
