Expert verdict

Brakes: 1.3× the national share

Brakes make up 27.2% of everything recorded on the 2005 Vauxhall Monaro, against 20.9% nationally — 6.3 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 85.6% — 13.2 points ahead of what its age and mileage predict.
When it fails, it costs. Only 6% 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.

Before your test

Three checks worth doing on a 2005 Monaro

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 suspension joints 2.9% of tests

“linkage ball joint dust cover ball joint dust cover severely deteriorated”

With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.
Check the brake pipes 1.8% 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.
Check the windscreen 1.8% 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.

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 2005 Monaro through its MOT

Across the 10 items that are recorded most often on this model, the average repair comes to £38–£90 — and 6% of those repairs are parts that cost under £30.

Average repair across the 10 common items: £38–£90
Cheapest common item: malfunction indicator lamp inoperative or…: £3–£12
Dearest common item: windscreen damaged: £80–£200
Common items a careful owner can do at home: 80%
Repairs that still cost under £30: 6%

Estimates from typical UK parts prices, weighted by how often each item appears in 452 MOT tests on this vehicle.
