Independent Pre-Purchase Vehicle Inspections
Licensed Ontario 310S technician comes to the vehicle. Full diagnostics, paint analysis, test drive, and a clear written report — so you know exactly what you’re buying.
What We Inspect
Comprehensive evaluation performed on-site at the seller’s location.
Full Diagnostic Scan
Professional Autel MaxiCOM scan across all modules. Stored, pending, and current fault codes identified and explained in plain language.
Paint Thickness Analysis
Digital readings on every panel to detect prior bodywork, refinishing, or panel replacement — even when the history report is clean.
Battery & Electrical
In-vehicle battery analysis including State of Health, measured vs rated CCA, cranking performance, and charging system check.
Test Drive Evaluation
Road test to assess engine response, transmission behaviour, steering feel, brake performance, and overall drivability.
Tires, Brakes & Visual
Tread depth, tire age (DOT), uneven wear, brake condition, underbody, engine bay, and exterior cosmetic assessment.
Detailed Digital Report
Clear written summary with findings, diagnostic results, paint analysis, photos of concern areas, and practical recommendations.
