It seems fairly obvious that the silver is 1:In better shape, 2:Costs less, 3:Has almost half the miles, 4:Is a year younger. Unless you absolutely have to have red/orange seats, you can buy a vinyl ironman sticker at most sign shops for real cheap, and a roof rack on here for around $400-$450 or so. To me the wear and tear you are going to save alone would be worth it to go with the silver, considering parts are not A:cheap, and B:readily available in general. With a vehicle this rare, you need all the help you can get. Another thing to consider from the aesthetic side is that with a grey/black interior, it matches the outside of a silver a lot better. I am fine with my reddish orange interior, but some people really aren't too fond of the more "sporty" look.
