Expert verdict
Body & chassis: 2.9× the national share
Body & chassis accounts for 16.4% of everything recorded on the 2007 Mazda Bt-50, against 5.6% nationally — 10.8 points above. Brakes are still the single largest share at 19.1%, but at 20.9% nationally that one is ordinary. Look underneath for corrosion near the jacking points and suspension mounts; surface rust is normal, flaking metal is not.

Where the Mazda Bt-50 is most common
Across all Bt-50 model years on record (2006–2010): 1,171 Mazda Bt-50 cars tested in a recordable postcode area, across 3,060 tests. Ashford (TN) has the most, with 40 cars tested there. Cars are counted by the postcode area of the MOT station, so this is where they were tested, not necessarily where their owners live.

The twenty areas with the most Mazda Bt-50 cars in the record, sorted by car count — sort the columns for a different question. Cars tested at a station whose postcode area could not be resolved are counted in the model's total but in no area, so the shares add up to slightly under 100% even across every area, and an area's cars are a subset of the model's. Pass rate is blank below 30 tests in an area, where a percentage is noise rather than a finding. How this model's pass rate varies by postcode →

What fails a 2007 Bt-50
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 2007 Bt-50
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 7.0% 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 lights 6.8% 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.
-
Check the brake pipes 4.5% of tests
“rigid brake pipes excessively corroded”
Brake pipes run under the car, usually in front of the rear wheels. Flaking or crusty metal is what fails; a light dusting of surface rust does not. Worth asking a garage to look while it is on a ramp.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
