It seems like new car dealers do a nice job of detailing their used vehicles (some of them). I recently went to a Nissan dealer and looked at some used maximas, they all smelled at least a little like new Nissan. Even the ones with cloth interiors were smelling great. I would imagine that it probably has something to do with the carpet and upholstry shampoo they use in their carpet extractors. Anyone know what a popular shampoo is for dealers? I'd like to get my cars smelling somewhat new again.
