Used-car pre-purchase inspection: is your quote fair?

A pre-purchase inspection (PPI) is an independent check of a used car before you buy it. Here's what a good one covers, what drives the price, and the red flags to watch for in a quote.

What a pre-buy inspection should cover

Engine: leaks, noises, belts, hoses, fluid condition, signs of overheating
Transmission and drivetrain: shift quality, fluid, CV joints/axles, driveline play
Brakes: pad and rotor wear, lines, fluid, parking brake
Steering and suspension: tie rods, ball joints, bushings, shocks/struts
Tires: tread depth, uneven wear, age
Underbody: rust, frame damage, prior repair or accident evidence
Electrical: battery, charging system, lights, accessories, warning lights
Diagnostic scan: stored and pending codes, readiness monitors
Body and interior: panel gaps, paint mismatch, water damage, A/C and heat
Road test: cold start, acceleration, braking, alignment, noises
A written report you get to keep

What affects the price

Factor	Why it matters	Fair range
Scope	A quick visual check costs less than a full multi-point inspection with a written report.	[Ryan fills in]
Diagnostic scan	A basic code read is quick; a full scan of all modules takes longer and needs better tools.	[Ryan fills in]
Test drive	A proper road test adds technician time.	[Ryan fills in]
Lift inspection	Getting the car in the air is the only real way to check the underbody, frame, leaks and suspension.	[Ryan fills in]
Specialty/European vehicles	Brand-specific scan tools, more complex systems and specialist knowledge can raise the price.	[Ryan fills in]
