I think that is a great idea people can't afford to buy new cars all of the time and we get upset when we buy a new car and see that a scratch has appeared. It always seems to happen right after you get it home from the car lot. That ticks me off so go for this I think it will be profittable. However do your research to see how much supplies will cost you and also come up with a solid business plan. This will help you on your path to success. Good luck.
