Expert verdict
Brakes: 1.7× the national share
Brakes make up 35.4% of everything recorded on the 2005 Cadillac Cts, against 20.9% nationally — 14.5 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 72.4% and this one manages 75.8% — 3.4 points ahead of what its age and mileage predict.
- Failures here tend to be cheap ones. 56% of the repairs this model fails on cost under £30 in parts. The pass rate matters less than what a bad afternoon at the test centre actually costs you.

What fails a 2005 Cts
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 2005 Cts
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 lights 8.6% of tests
“malfunction indicator lamp inoperative or indicates a malfunction”
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 windscreen 4.7% 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 brake pipes 3.9% 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.
