Skipping the pre-buy inspection is the fastest way to turn a profitable flip into a money pit. This 15-point checklist covers everything you need to verify before buying any vehicle for resale.
Print this out. Keep it in your glovebox. Run through it on every single deal.
Section 1: Title & History (Points 1-4)
1. Clean Title Verification
Check the physical title for: branded title status (salvage, rebuilt, flood, lemon), matching VIN to the vehicle, lien releases, and correct owner name. A branded title kills 30-50% of your resale value.
2. VIN History Report
Run the VIN through Carfax or AutoCheck ($10-$40). Look for: accident history, number of owners, service records, title brands, and odometer discrepancy. A clean history report is also a selling tool.
3. Odometer Verification
Compare the title mileage to the actual odometer. Check for signs of tampering: misaligned digits, scratches around the instrument cluster, or excessive wear inconsistent with stated mileage.
4. Recall Check
Run the VIN at NHTSA.gov for open recalls. Unaddressed safety recalls can be a liability issue and a negotiating tool. Dealers will fix recalls for free.
Section 2: Mechanical (Points 5-9)
5. OBD2 Scan
Plug in your OBD2 scanner and check for stored and pending codes. Even if the check engine light is off, codes may be stored. Pay special attention to transmission, emission, and catalytic converter codes.
6. Engine Assessment
Cold start the engine (ask the seller not to warm it up). Listen for: knocking, ticking, rough idle, or white/blue exhaust smoke. Check oil — milky color means head gasket failure. Check coolant level (low = possible leak or head gasket).
7. Transmission Test
Drive through all gears. For automatics: shifts should be smooth with no slipping, jerking, or delayed engagement. For manuals: clutch should engage smoothly with no grinding. Transmission repairs are deal-killers — budget $2,000-$4,000 if needed.
8. Brake Inspection
Test brakes at various speeds. Listen for grinding or squealing. Check pad thickness visually through the wheel spokes. Verify the car stops straight (no pulling). Budget $150-$400 for pads and rotors per axle.
9. Suspension & Steering
Drive over bumps — listen for clunking or rattling. Check for uneven tire wear (indicates alignment or suspension issues). Turn the steering wheel lock-to-lock — should be smooth with no play or grinding.
Section 3: Body & Interior (Points 10-12)
10. Paint Thickness Test
Use a paint thickness gauge on every panel. Factory paint is typically 100-150 microns. Readings over 200 indicate repaint. Readings over 500 indicate body filler (Bondo). Walk away from heavy body work.
11. Rust Inspection
Check wheel wells, rocker panels, door bottoms, trunk floor, and undercarriage. Surface rust is cosmetic; structural rust is a deal-breaker. In northern states, rust inspection is critical.
12. Interior Condition
Check seats (rips, stains, wear), dashboard (cracks, warping), carpet (stains, dampness — flood indicator), headliner (sagging), and all electrical: windows, locks, AC, heat, radio, lights.
Section 4: Financial (Points 13-15)
13. Market Value Research
Check KBB, Edmunds, and Facebook Marketplace for comparable vehicles. Know the retail value BEFORE you negotiate. Never buy a car you have not priced.
14. Repair Cost Estimate
List every repair needed with estimated cost. Add 15% contingency for surprises. Total repair cost must leave room for profit at the expected sale price.
15. ROI Calculation
Run the numbers through our car flip calculator. Include ALL costs: purchase + repairs + holding + transaction fees. If ROI is below 25%, think twice. Below 10%, walk away.
