A pre-purchase inspection (PPI) usually costs between $100 and $200 at a mechanic, around $40 for a standalone VIN history report, and from $9.99 with an app like MotoPPI (first check free). Mobile inspectors who come to the car typically charge $150-$250. So the honest answer to “how much is a PPI?” is: anywhere from under ten dollars to a few hundred, depending on how much of the work is done by a person versus done by you with the right tool.
If you’re searching for “PPI cost”, “cheap PPI”, or the “cheapest PPI company”, this 2026 guide breaks down every option, what you actually get for the money, and how to pick the best PPI service for your situation, without either overpaying or skipping the checks that matter.
PPI cost comparison (2026)
| Option | Typical cost | What you get | Best for |
|---|---|---|---|
| Mechanic PPI (shop) | $100-$200 | Full physical inspection on a lift, mechanical diagnostics. No history report. Appointment usually days out. | Final deep check before buying a keeper |
| Mobile PPI inspector | $150-$250 | Inspector travels to the car, physical check on-site. Convenient but pricey, no lift. | Cars far away or private sellers who won’t drive to a shop |
| Standalone history report | ~$40 | A VIN document: title brands, salvage, theft, odometer, recalls. No physical inspection, no advice. | Fast desk-check of the paper trail only |
| MotoPPI app | from $9.99 (first check free) | VIN history across 20+ databases + model-specific inspection checklist + repair cost estimates + negotiation script | A fast first-pass screen before you commit time or money |
The mechanic is the most thorough and the most expensive. The history report is cheap but it is just data. The gap in the middle, full history plus a guided physical checklist plus pricing, without booking a shop, is what MotoPPI was built to fill as a first-pass screen.
What drives the price of a PPI?
Not every PPI costs the same, and the number on the invoice comes down to a few factors:
- How much human labor is involved. A mechanic putting a car on a lift for an hour is the single biggest cost driver. An app that guides you through the same checklist removes that labor cost.
- Whether it includes a history report. Many shop PPIs don’t pull the VIN history, so you pay ~$40 more separately. Bundled services cost less overall.
- Travel. Mobile inspectors bill for the drive to the seller. The further the car, the higher the fee.
- The car itself. Exotics, classics, and diesels with complex emissions systems cost more to inspect than a five-year-old commuter.
- Region. Prices in major metros (Los Angeles, New York, London) run 30-50% higher than in smaller towns, mostly because shop labor rates differ.
Mechanic vs mobile inspector vs app
These three options aren’t really competitors, they solve different parts of the same problem, and the smartest buyers use them in sequence.
Mechanic PPI
The gold standard for deep mechanical diagnostics: compression, leaks, suspension play, computer fault codes, brakes, and anything that needs a lift. If you’ve already decided a car is worth buying, this is the check that confirms it. The downsides are cost, the wait for an appointment, and the fact that most shops skip the VIN history entirely.
Mobile PPI inspector
A professional who comes to the car. Great when the vehicle is far away or the seller won’t bring it in. You pay a premium for the convenience and usually don’t get lift-level diagnostics. A solid choice for a serious buy you can’t reach yourself.
App-based PPI
An app like MotoPPI runs the VIN history and walks you through a model-specific inspection checklist in minutes, then estimates repair costs and hands you a negotiation script. It’s the fast first pass: it tells you whether a car is even worth a mechanic’s time, and catches the paper-trail traps (rebuilt salvage listed as clean, rolled-back odometer) that a physical inspection alone can miss. It works alongside professionals, not instead of them.
Is a cheap PPI worth it?
Yes, and here’s the counterintuitive part: the cheaper the car, the more important the check. When someone is selling a $4,000 car, there’s often a reason the price is low, and it’s usually hidden. Paying $200 to inspect a $4,000 car can feel disproportionate; paying $10 to avoid a $5,000 mistake never does.
A cheap PPI is only a bad idea if “cheap” means “incomplete”. A $40 history report with no physical check tells you the paperwork is clean but nothing about the timing chain. A shop inspection with no VIN pull tells you the car drives fine but nothing about the salvage title. The trick is getting all the pieces cheaply, not skipping pieces to save money.
How to choose the best PPI service
Whatever you pick, judge it on these:
- Does it pull title and salvage history by VIN? A PPI that skips this doesn’t protect you from the single most expensive trap, a rebuilt wreck sold as clean.
- Does it tell you what to do, not just what it found? Raw data is useless if you can’t tell a dealbreaker from a $50 fix.
- Is the cost proportional to the car? Match the spend to the risk.
- How fast is it? A seller pushing for a quick deal won’t wait three days for your mechanic’s slot. A first-pass screen you can run on your phone at the curb keeps you in the game.

The cheapest complete PPI for most buyers
For a one-off purchase, the best value is to screen first, then spend. Run an app-based check that combines VIN history, a guided checklist, and repair estimates for under $10, rule out the obvious lemons, and then pay a mechanic only for the cars that survive the first pass. You stop wasting $150 inspection fees on cars that were never worth buying.
That’s the whole idea behind MotoPPI: a complete first-pass pre-purchase inspection from your phone, from $9.99, with the first check free. It doesn’t replace your mechanic, it makes sure you only pay one when it’s worth it. Download it on the App Store and screen your first car before you decide.
