How much should I spend on car detailing? At Shamerrific Shine Pro Auto Spa getting your car detailed can cost anywhere from $70 for a hand wash, and from $200-600 for a full interior and exterior clean. It depends on the size of your vehicle and the number of services you receive. Before you shell out, consider ways to get your vehicle feeling brand new without the additional price. Why pay taxes on a new vehicle when you can get yours looking new for much less.
