Pre-Purchase Vehicle Inspection: What Shops Check and What to Charge

Pre-purchase inspections (PPIs) are one of the most profitable, least time-consuming services shops can offer. A buyer is about to make a five-figure decision on a used vehicle. They'll pay $150–$300 for a thorough inspection from a trusted shop. It typically takes 60–90 minutes, requires no parts, and generates high-margin labor revenue.

What to Include in a Pre-Purchase Inspection

A complete PPI covers the major systems that could fail in the first year of ownership. You're not doing a full restoration evaluation — you're identifying immediate concerns and upcoming maintenance.

• Engine: Start, idle quality, unusual sounds, fluid leaks, battery condition
• Transmission: Shift smoothness (manual and automatic), fluid color and smell
• Brakes: Pad thickness, rotor condition, fluid leaks, brake feel and responsiveness
• Suspension: Strut condition, suspension bushing wear, alignment clues
• Tires: Tread depth, wear patterns, age (sidewall date codes older than 6 years)
• Cooling system: Radiator leaks, hose condition, coolant color
• Belts and hoses: Cracks, age, replacement needs
• Lights and electrical: All lights functioning, battery load test
• Undercarriage: Rust, welding repairs, accident evidence
• Interior: AC/heat function, window operation, dashboard warning lights

Pricing Your Pre-Purchase Inspection Service

Charge based on your local market and shop labor rate. Most shops charge $100–$300 depending on vehicle type and region. A $200 flat fee is standard for a complete inspection. Some shops charge $150 for basic (30 min) and $250 for comprehensive (90 min). Include a detailed written or digital report with your findings and recommendations.

Set Expectations Upfront

Buyers often expect you to diagnose every potential issue. Be clear about the scope: This is a visual and mechanical inspection, not a full diagnostic. You're identifying immediate concerns and likely maintenance within the next 1–2 years, not predicting repairs 5 years from now. Some shops offer a discount if the buyer proceeds with you for repairs, which incentivizes referrals.

Documentation Matters

Your inspection report is your liability protection. Document everything with photos and notes. Include your inspection checklist, any red flags you found, maintenance recommendations, and estimated costs for repairs you recommend. A professional report also builds trust with the customer and can be used to justify a higher inspection fee.
