My Dodge Charger had pet hair everywhere. You would never know now. Would book again. Rescheduling once was a minor hassle.

They treated my BMW X5 like it was their own car. The leather was conditioned and looks and feels great.

Booked a mobile detail in Brookings and the van pulled up right on time. The interior smelled brand new when they finished.

They detailed my Acura MDX at my office parking lot in Brookings. They did not rush a single step.

Mobile detailing that comes to you in Brookings — exactly what I needed. Great job on the exterior. The interior was good, not perfect.

Had them out to my place in Brookings for a ceramic coating on my BMW 3 Series. Would book again. Rescheduling once was a minor hassle.

They showed up late and rushed the last part of the job. Nobody answered my messages for two days.
