Over the last 20 years, Classy Chassis Car Wash's clientele has morphed from '92 Mustangs to 2012 hybrids. But no matter the make, model, or year of the vehicles that roll onto the lot, Chassis's staff of technicians and detailers stick to a consistent formula of washing, waxing, and shampooing cars in order to keep them pristine. A slate of wash packages incorporates rinses, tunnel waxes, and tire shines in the pursuit of that perfect gleaming finish. On the detailing end, technicians coax a blinding shine from the exterior with high-speed buffers, gild the newly minted colors in paint sealants, and soak the upholstery in shampoos. Even engines can join in on the fun as they get a wash and shine to impress mechanics and inspire pistons to incorporate graceful dance moves into their mechanical repertoire.
