What Vauxhall Cavalier Owners Should Watch For
Based on the MOT test data for the Vauxhall Cavalier, here are the key areas to pay attention to before your MOT:
- Lamps & Electrics (7.0% failure risk) — Walk around the car and check every bulb — headlights, brake lights, indicators, fog lights, and number plate lights. This is one of the cheapest and easiest fixes.
- Suspension (6.5% failure risk) — Look for leaking shock absorbers, worn bushes, and damaged springs. A bouncing or uneven ride often signals problems.
- Body & Chassis (5.5% failure risk) — Inspect the underside and sills for rust holes, particularly around structural mounting points. Corrosion that weakens the structure within 30cm of a mounting point is an automatic fail.
Many of these issues are inexpensive to fix when caught early. A pre-MOT inspection at a local garage typically costs £20–£40 and can save you the cost of a retest (£15–£30) plus the inconvenience of a failed MOT.
