The MOT pass rate is one signal, not the whole story. An MOT checks safety and emissions on the day of the test. It doesn't record gearbox or engine faults, and a pass rate also reflects mileage and upkeep, so the table shows median mileage too. Whatever the year, the car in front of you matters more than its model's average.

Porsche 911 MOT pass rate by year

Year is when the car was first used. Older vehicles fail more often, so each year is compared with all vehicles first used that year.

Tests are initial MOT tests in 2025, not retests. Median miles is the middle odometer reading at the test: half had more, half had less. ± is the 95% margin of error in points (Wilson interval): a difference smaller than that could be chance. Years without a link have fewer than 10,000 tests, so they are listed here but don't have their own page.

When a car's mileage doesn't add up

After an MOT advisory

Porsche 911 cars that passed their 2024 MOT first time with an advisory, and what their next MOT found, against similar cars that passed with nothing noted in that area. All first-use years together.

Tyres

Of Porsche 911 cars that passed their 2024 MOT with a tyre advisory and came back for their next MOT 10–14 months later, 6.3% failed on tyres, against 1.8% of similar cars with nothing noted. Based on 3,040 and 25,533 cars.

Similar cars are the same model, first-use year and mileage band. Areas are the DVSA's top-level groups, so the later fail may not be the fault that was advised. These figures describe what happened to these cars. They don't show what a repair would have changed.

Porsche 911 questions

Which Porsche 911 years have lower MOT pass rates?

Compared with all vehicles first used in the same year, no model year is clearly below average. Above average: 1999 and 2001–2022. A pass rate is one signal: it also reflects mileage and upkeep, and doesn't record engine or gearbox faults.

Is the Porsche 911 reliable?

MOT results show only part of the picture. In 2025, 89.7% of initial MOT tests on Porsche 911 cars were passed with no repairs, against a same-age average of 67.6%. That is 22.2 points above average. An MOT checks safety and emissions on the day of the test. It doesn't measure breakdowns, engine or gearbox faults, or repair costs.

What mileage is normal for a 10-year-old Porsche 911?

At their 2025 MOT tests, Porsche 911 cars first used in 2015, about 10 years old, had a median of 33,000 miles. Half had more and half had less.

How do I check a specific 911's MOT history?

Enter its registration in our free check. It lists that car's own MOT results, the faults and advisories recorded and the mileage at each test, and flags repeated advisories and mileage that goes down.

What MOT data can't tell you about any Porsche 911

Outstanding finance, write-offs, theft and plate changes aren't in MOT records. For a particular car, you need a history check.
