About This Data
The 2020 Porsche Boxster has an MOT pass rate of 94.7% based on 1,388 tests — well above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 17,011 miles on the odometer. With a 5.3% failure rate, the 2020 Boxster is rated as "Excellent" for MOT reliability.
If you own or are considering buying a 2020 Porsche Boxster, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to tyres: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating. With relatively low average mileage of 17,011 miles, many of these vehicles are still in good mechanical condition.
Tyres — 2.8% of failures
Tyres issues account for 2.8% of MOT failures on 2020 Porsche Boxster models. Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure. Tyres are one of the most common and easiest-to-prevent MOT failures. Typical repair costs: £50–200 per tyre. Pre-MOT check: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects.

Lamps, reflectors and electrical equipment — 0.8% of failures
Lamps, reflectors and electrical equipment issues account for 0.8% of MOT failures on 2020 Porsche Boxster models. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail.
