Expert verdict
Brakes: 1.6× the national share
Brakes make up 33.6% of everything recorded on the 2009 Porsche Boxster, against 20.9% nationally — 12.7 points above. Have the discs and pads measured rather than glanced at, and ask whether the handbrake holds on a slope.
- Beats its own age and mileage. Once you allow for how old and how far these cars have been driven, the expected pass rate is 74.0% and this one manages 91.4% — 17.4 points ahead of what its age and mileage predict.
- When it fails, it costs. Only 35% of this model’s typical repairs come in under £30 in parts — the failures here tend to be the kind that need a garage rather than a bulb.

What fails a 2009 Boxster
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2009 Boxster
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
-
Check the windscreen 2.0% of tests
“windscreen damaged”
Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.
-
Check the coil springs 1.3% of tests
“coil spring fractured or broken”
Look up inside each wheel arch with a torch, all the way round the spring. A snapped spring usually breaks at the very bottom coil, where a quick glance will not reach.
-
Check the lights 0.9% of tests
“registration plate lamp(s) inoperative in the case of multiple lamps or light sources”
Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
What it costs to get a 2009 Boxster through its MOT
Across the 10 items that are recorded most often on this model, the average repair comes to £38–£94 — and 35% of those repairs are parts that cost under £30.
