This page is specifically about commissioning and using an independent mechanic’s inspection report. For a general walk-around checklist, see Used Car Checklist in Ireland.
An independent inspection is most valuable when it answers a specific question before money changes hands. It can identify visible wear, leaks, warning lights, poor repairs, tyre condition and evidence that a component may need attention. It cannot guarantee that a car will not develop a fault next month, and it does not replace a history check or a review of ownership documents.
Ask the mechanic or inspection provider what is included before paying. A basic visual inspection may not include a lift, diagnostic scan, road test or written report. Compare that with a more detailed pre-purchase service that checks the underside and records defects. Confirm whether the seller will allow the car to be taken to a workshop, whether the inspection is independent of the seller and who is responsible if the car is damaged during testing.
The CCPC recommends having a used car examined by an expert such as a mechanic, particularly in a private sale. The NCT is not a substitute: NCTS describes it as a check of specified roadworthiness conditions at the time of the test, without dismantling, and explicitly says it is not a warranty. A recent pass therefore does not establish the condition of the clutch, timing system, transmission or future maintenance needs.
Use the report to make one of three decisions: proceed at the agreed price, renegotiate against documented work, or walk away if the findings conflict with the seller’s description. Request estimates for safety-critical or imminent repairs rather than negotiating from a vague list. Keep the inspection report with the advert, history findings and service invoices so you can compare the whole picture.
If a seller refuses any independent check, that is not proof of a fault, but it increases uncertainty. Decide whether the price and remaining evidence justify taking that risk.
