Buying a used car is a big decision, and while a good deal can save you money, a bad one could cost you far more in repairs down the line. That’s where a Pre Purchase Inspection (PPI) comes in. For UK drivers, it's one of the most valuable steps in the car-buying process—especially when purchasing privately or from smaller dealers.
At Checkmot.com, we help you make smarter car-buying decisions, and in this article, we break down what a pre-purchase inspection is, why it matters, and what to expect.
A Pre Purchase Inspection is a detailed assessment carried out by a qualified mechanic or inspection service before you commit to buying a used vehicle. It’s designed to uncover any existing faults or signs of future problems that may not be visible during a simple test drive or visual check.
The inspection typically includes a review of the engine, brakes, tyres, suspension, electrical systems, and even the bodywork. In some cases, it may also include a road test and diagnostic scan, depending on the level of service chosen.
Used cars, especially those out of car warranty, come with an element of risk. Sellers might not disclose every issue—whether intentionally or simply due to lack of awareness. A pre-purchase inspection helps reduce that risk by giving you a full picture of the vehicle’s condition.
It can highlight issues like:
By knowing these things in advance, you can either walk away or negotiate a fairer price.
A PPI is especially useful in the following scenarios:
If the car seems too cheap for its age and mileage, that’s also a red flag worth investigating further.
Prices vary depending on the level of inspection and who performs it. Basic checks might start around £100, while a comprehensive inspection with road testing and diagnostics could cost upwards of £200. While it may seem like an added expense, it could save you from buying a car that needs £1,000+ in immediate repairs.
Before you even book an inspection, use Checkmot.com to view the car’s full MOT history. This will give you insight into past advisories, failures, and potential long-term issues. It’s a simple, free way to assess whether the car is worth a closer look.
A Pre Purchase Inspection gives you peace of mind, protects your wallet, and arms you with the information needed to make a sound investment. At Checkmot.com, we recommend every used car buyer takes this important step—because being informed today means fewer regrets tomorrow.
