Mobile Detail.
Professional mobile + in-shop auto detailing. Wash & wax, interior care, machine paint correction, and pro-grade ceramic coatings — done by hand at your home, office, or our shop.

Premium Wash & Wax

Paint Correction + Ceramic
Machine polishing reduces swirls, oxidation, and surface defects — restoring clarity and gloss. Then we seal the paint with a professional ceramic coating: hardness, hydrophobic beading, easier maintenance.

Local detailer. Real care, real results.
Koster Mobile Detail is a Sioux Falls auto-detailing studio focused on the details that matter — the swirl you can only see under the LED, the dust trapped in the seam, the wheel face you forgot the dealer ever cleaned.
- Mobile + in-shop
We come to your home or office in the Sioux Falls area, or you can drop it at the shop on West Tickman Street.
- Hands-on, never automated
Two-bucket hand wash, machine polishing by feel, ceramic coatings applied panel-by-panel. No automated brushes.
- Sioux Falls local
Owner-operated. Every vehicle gets the same focus and care — daily drivers, weekend toys, motorcycles, all welcome.
Real cars. Real driveways. Real receipts.
Honest pricing. Custom quotes always free.

What clients say after the keys go back.
"Masen came to my house with a full setup. The Civic looks better than the day I bought it — interior, paint correction, ceramic, all of it."
"Booked the Premium Clean & Vac before a road trip. Vacuum job was insane — I had no idea how much sand was under those seats."
"The ceramic on my Mustang still beads like day one six months later. Easy texts, fair price, total pro."
"Got the Wash & Wax done in my driveway while I worked. Showed up clean, left everything cleaner. Highly recommend."
