Checking more than one car? Second and every further car 20% off.

Extended requires the seller's consent to a ~60-minute test drive - confirm this with the seller before booking. If it turns out impossible on site, we perform the Standard scope and refund the difference or credit it towards another service.

Check the travel cost to the car

Distances are approximate (road from Katowice). We confirm the exact cost when booking.

Travel: Katowice and surroundings up to 50 km - included in the inspection price. Beyond 50 km from Katowice: 1 zł per km (counted both ways).

Frequently Asked Questions

What does a pre-purchase inspection cover?

A comprehensive check: paint thickness measurement across the whole body, full computer diagnostics of all modules, mileage verification in the control units, assessment of the engine, gearbox, suspension and brakes, underbody inspection, a test drive and vehicle history analysis. We check from 200 to over 300 inspection points.

Will you detect a rolled-back odometer or hidden tuning?

That's our speciality. We compare the mileage against records in multiple control units (not just the dash), and verify the engine software for modifications - we detect chip tuning, disabled emission systems (EGR/DPF/AdBlue) and traces of tampering the seller "forgot" to mention.

How long does the inspection take and what do I get?

A full inspection takes 2-3 hours. You receive a clear report with photo documentation, a list of faults, estimated repair costs and our recommendation: buy, negotiate or run.

Is it worth paying a few hundred zlotys for an inspection?

The average hidden fault in a used car costs many times more than the inspection. The report is also a negotiating tool - our customers regularly knock the purchase price down by amounts far exceeding the cost of the check.

I'm buying a used EV or hybrid - can you check it?

Yes, and it's definitely worth it: the most expensive part of an EV is the battery, whose condition you can't judge by eye. We run an SOH test, cell balance analysis and charging history review. A result below ~80% SOH is a signal for hard price negotiation or walking away.

The seller won't agree to an inspection. What does that mean?

A red flag. An honest seller of a sound car has no reason to refuse an inspection - refusal usually means there's something to hide. We advise looking elsewhere.
