Boasting more than 90 years of combined auto-body, restoration, and detailing experience, Diamond Auto Spa cleans the crevices of cars with professional care. Diamond’s employees can lavish roadsters with a 30-minute wash and wax, whisking vehicles by hand with cleaners that contain wax components and scouring every corner of the car, down to the family of field mice singing show tunes in the wheel well. Available for cars (an $85 value), small SUVs (a $95 value), and large SUVs or trucks (a $105 value), Diamond’s mini detail begins with a vacuum of interior carpet and upholstery before scouring the dashboard and center console. Over the course of four hours, Diamond’s crack cleaners will hand wash exteriors, tires, and rims, removing insects and tar from lower-body panels and applying cleaning wax for protection.

Diamond’s complete detail scours road ponies with an extensive three-step process, removing interior stains and cleaning crevices with an air gun. After shampooing interiors for filth and floor dandruff, employees will treat leather with a pH-balanced formula and wash windows until they are smudge- and streak-free. After a complete detailing of your car (a $165 value), small SUV (a $180 value), or large SUV or truck (a $195–$225 value), passing pedestrians will line up around the corner to admire your roadster’s polished wood interiors and try to eat off your steam-cleaned engine block.
