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 Boxster 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

Does mileage matter?

Porsche Boxster first-time pass rates by the mileage at the initial test, all years together, against all vehicles of the same age and mileage.

94.3% of Porsche Boxster tests under 30,000 miles passed first time, against 67.5% at 120,000 miles or more. For all vehicles of the same age and mileage, the figures are 84.1% and 56.0%.

Miles at the test	Tests	Passed first time	Against all vehicles, same age and mileage
Under 30,000	3,126	94.3%±0.9	+10.2 ptsall: 84.1%
30,000–59,999	7,574	88.0%±0.8	+16.3 ptsall: 71.6%
60,000–89,999	8,053	78.8%±1.0	+17.3 ptsall: 61.5%
90,000–119,999	5,130	72.4%±1.3	+15.0 ptsall: 57.3%
120,000 or more	1,957	67.5%±2.2	+11.4 ptsall: 56.0%

Against all vehicles of the same age and mileage, Boxster tests were above average in every band shown.

Mileage is only one factor. How a car has been driven and looked after matters too. These figures show an association across all Porsche Boxster tests in 2025, not what mileage does to a particular car.

Mileage is the odometer reading at the initial test. Each band is compared with all vehicles first used in the same year with a reading in the same band, weighted by this model's own tests in each year. Bands need at least 1,000 tests. 40 tests (0.2%) had no usable odometer reading and are left out. How we count

After an MOT advisory

Porsche Boxster 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 Boxster cars that passed their 2024 MOT with a tyre advisory and came back for their next MOT 10–14 months later, 6.1% failed on tyres, against 2.0% of similar cars with nothing noted. Based on 2,741 and 16,313 cars.

Cars not tested again in that window are not included: 15.4% of those with a tyre advisory and 14.3% of the others.

Brakes

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 Boxster questions

Which Porsche Boxster 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: 1999–2008, 2012–2016 and 2018. A pass rate is one signal: it also reflects mileage and upkeep, and doesn't record engine or gearbox faults.

Is the Porsche Boxster reliable?

MOT results show only part of the picture. In 2025, 81.2% of initial MOT tests on Porsche Boxster cars were passed with no repairs, against a same-age average of 62.2%. That is 19.0 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 Boxster?

At their 2025 MOT tests, Porsche Boxster cars first used in 2015, about 10 years old, had a median of 35,200 miles. Half had more and half had less.

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

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