Real Diagnosis. Honest Answers.
When something’s wrong with your truck - a check-engine light, a new vibration, a noise that wasn’t there last week - you want answers, not a guess.
At G&M Motorsports, we run real diagnostics with OEM-level scan tools, not just a cheap code reader plugged in for two minutes. We pull live data, we test the affected systems under load, and we tell you exactly what’s wrong, what it’ll cost to fix, and whether it’s something you need to handle now or can wait. No upsells. No fishing expeditions.
Pre-Purchase Inspections That Save You From Expensive Mistakes.
Buying a used truck - especially a lifted or modified one - is a minefield. Aftermarket installs done poorly, hidden frame damage, transmission slip patterns, suspension geometry off after a previous lift kit. We’ve seen it all because we’ve fixed it all.
Our pre-purchase inspections include a full mechanical evaluation, suspension and lift-kit assessment, electrical and computer system check, and a frame and undercarriage inspection. You get a written report with photos, recommendations, and an honest opinion on whether the truck is worth what they’re asking.
Inside Every G&M Inspection
Why Choose G&M Motorsports:
We have 15 years of build history to draw on. When we evaluate a used lifted truck, we know what a clean install looks like vs. a rushed one. We know what a typical Carli build holds up to and what a knock-off lift kit looks like after a year. That experience is the reason customers from across Arizona drive to us for pre-purchase inspections, even on trucks they’re buying out-of-state.
Our Process:
Pre-purchase: drop off the truck or meet us with the seller. We inspect, we test-drive, we scan, we photograph, we deliver a written report.
Diagnostic appointment: bring the truck, we’ll run live data while you wait or while we keep it for the day. Either way, you get a clear answer in plain language - not service-writer guesswork.
Key Benefits:
• OEM-level diagnostic equipment (not a cheap scan tool)
• 15 years of lifted-truck and modified-vehicle experience
• Written pre-purchase reports with photos and recommendations
• Live-data analysis under load, not just static fault codes
• Honest answers - including "this isn’t worth fixing"
