Used vehicle inspection checklist (pre-purchase)
Updated · Reviewed by Israel Margulies, founder and CEO of High Point GPS
A pre-purchase checklist for buying a used truck, van or machine: the paperwork and VIN, the body and frame, engine and transmission, brakes, tires, electrical, fluids and leaks, the hour meter or odometer, and a test drive or operating test.
A used vehicle can be a good buy or someone else's problem. Checking the paperwork, the frame and the drivetrain before you pay, and driving or operating it under load, finds most of the expensive surprises. For a big purchase, add an inspection by a mechanic you choose.
Ask for the service records. A truck or machine with a steady history of oil changes and repairs is easier to trust than a cleaner one with none. Check open safety recalls by VIN on the NHTSA recall lookup for on-road vehicles.

- Signs of flood damage (silt, rust under the dash)
Engine

- No knocking, ticking or smoke
- Oil level and condition (no milky oil)
- Coolant level and condition
- Belts and hoses
- Leaks under the engine
Transmission and driveline
- Shifts smoothly in every gear
- Clutch engages correctly (manual)
- No grinding or clunking
- 4WD or PTO engages (where fitted)
- Fluid level and condition
Brakes, steering and suspension
- Brakes stop straight without pulling or noise
- Parking brake holds
- Steering: no excessive play
- Shocks, springs and bushings
- Air system builds and holds pressure (air brakes)
Tires and wheels
- Tread depth on every tire
- Even wear (no cupping or one-sided wear)
- Sidewall cuts or bulges
- Wheels and lug nuts
Electrical
- Battery and charging
- Lights, signals and reflectors
- Gauges and warning lights
- Heater, A/C and wipers
- Diagnostic codes scanned
Test drive or operation
- Drives or operates under load
- Hydraulics lift and hold (machines)
- No overheating
- Odometer or hour meter works and matches records
Fill it in the right way
- Check the paperwork and the VIN first; if they don't match, stop there.
- Look at the vehicle cold, before the seller warms it up, so starting problems show.
- Walk around and underneath for frame damage, rust and leaks.
- Check fluids, belts and hoses, then start it and listen.
- Drive it or operate it under load for long enough to warm up fully.
- Scan for diagnostic codes, then decide: buy, don't buy, or offer less for the repairs you found.
Tips
- Inspect in daylight and on dry ground, where leaks and paint differences show.
- Bring a code reader; cleared codes and warning lights that never come on are red flags.
- Hours tell more than miles on machines and trucks that idle or work in place.
- Get a written list of anything the seller agrees to fix before you pay.
Do it in FleetZap
- Once you buy it, add the vehicle to FleetZap with its VIN, odometer, hour meter and documents.
- Set PM schedules by miles, hours or the calendar from day one, so its history starts clean.
- Parts, labor and outside repair costs from every work order roll up to the vehicle, which shows whether it was a good buy.
- Drivers scan its QR label to do pre-trip checks on their phone; a failed item opens a repair work order.
