Porsche Panamera: MOT pass rate and reliability data

The Porsche Panamera passes its MOT first time more often than the average UK car, by 11.1 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 6,608 individual Porsche Panamera tests. Nothing here is an estimate or a survey.

The numbers

What this means if you are buying one

A 87.8% first-time pass rate means roughly 12 in every 100 Porsche Panameras presented for MOT fail on the first attempt. That is better than average, so a well-kept example is a reasonably safe used buy. The average Porsche Panamera tested had covered 62,688 miles and was built around 2016.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. The Porsche Panamera sits 11.1 points above the national average, ranked 1,013 of 2,005 models. On one bought as repairable salvage, the mechanical side is less likely to spring surprises, so your repair estimate should hold up reasonably well.

Before you bid: run the lot through the analyzer, check the car's own record, check the mileage, decode the VIN, and if it carries a marker use the write-off value calculator. Or compare it against another model.

Looking at a specific Porsche Panamera rather than the model in general? The free check covers its MOT and mileage history, and the full HPI report confirms the insurance write-off category, outstanding finance and whether it is recorded stolen, from licensed data for 5 credits. Already own one that has been damaged? Work out whether fixing it beats selling it with the repair or scrap calculator, and see recorded closing bids for damaged Porsche Panameras at UK salvage auction.
