Know What You're Buying — Independent Inspections for Used Trucks and Diesels | MST Motorsports | Washington UT
MST Motorsports performs pre-purchase inspections for buyers of used trucks, diesels, Jeeps, Broncos, and SUVs across Washington, St George, and Hurricane. Spending an hour and a couple hundred dollars on an independent inspection before you buy can save you thousands — used trucks (especially diesels) hide expensive problems behind a fresh wash and a hopeful seller.
Our inspection process covers the mechanical, electrical, and structural condition of the vehicle, plus a scan tool review and a road test. You get a written report with findings, photos, and our honest opinion on whether the truck is worth what's being asked.

Engine condition and leaks, transmission and transfer case operation, drivetrain (axles, differentials, driveshafts, U-joints), suspension and steering components, brake system condition and pad/rotor life, frame and undercarriage inspection for rust, damage, or evidence of off-road abuse, body and paint inspection for hidden collision damage, tire condition and matching, fluid condition (engine oil, coolant, transmission fluid, gear oil), and electrical system check.
On diesels, we add specific checks: blow-by inspection, EGR and DPF status, glow plug operation, coolant and oil contamination cross-checks, and a full scan for stored and pending codes — including codes that have been recently cleared (a common seller trick).
We connect OE-level scan tools and pull a complete diagnostic report — current codes, pending codes, freeze frame data, readiness monitor status, and (on supported platforms) recent code clear history. If a seller cleared codes 50 miles ago, we'll see it.
The road test covers acceleration, transmission shift quality, brake operation, steering and tracking, drivetrain noise, and overall feel. A surprising number of problems only show up under load or at speed — that's why we drive every truck we inspect.
You get a written inspection report covering what we found, what's normal wear, what's an immediate concern, and what's likely to need attention in the near future. We include estimated costs to address the major findings so you can negotiate price or walk away with confidence.
We work for you, not the seller. If the truck has problems, we'll tell you. If it checks out clean, we'll tell you that too. Our job is to give you the information you need to make a good decision.
Don't buy a used truck blind. Schedule an independent pre-purchase inspection with MST Motorsports and know what you're getting before you sign. Serving Washington, St George, Hurricane, and the surrounding area.
