Locally owned. The same clean, every wash.

Pony Express is locally owned and operated by the Benson family. They live and work in the communities we serve. We are not trying to be the biggest car wash. We are trying to be the reliable one. You know what to expect on each visit: a quick wash and a car that comes out clean.

Owned and run by people who live here.

They are not absentee owners or out-of-state operators. They raise their families here, and they know what local roads do to a car, from summer bugs and dust to winter salt.

About us

Built around the process.

Engineer the process correctly and good results follow every time. We use equipment built for the job and products that are safe for your car, and we adjust both for the season.
