I buy everything I can used, within reason. Cosmetic parts especially, as long as I don't need to do extensive repairs to them. Paint's cheap. Labor's cheaper. I just wouldn't expect big numbers for resale value. It's luck if a buyer and seller share the same paint scheme. Otherwise places like AM sell cosmetic parts pre-painted. I look at cost of the part, cost of paint, how long will it take me vs price. I picked up my chin spoiler for $80, cost me another $20 to paint it. Got my GT500 wing from a take-off ebay seller for $50, was originally red, had to sand it down and another $20~$30 in paint. Used cosmetic parts are awesome at the right price, otherwise it's more favorable to buy new, less work and less flaws. If there's ever a fitment defect, it can be sent back.
