Vauxhall Cavalier Gsi 16v (1991)
1991 Vauxhall Cavalier Gsi 16v
CarHunch is tracking 1,540 1991 Vauxhall Cavalier Gsi 16v vehicles on UK roads. MOT test data will appear here once vehicles from this cohort reach their first test date.
The 1991 Vauxhall Cavalier GSI 16V is a serious reliability concern: just 30% pass their MOT first time, versus the UK average of 80%. No dangerous defects were recorded in this cohort, which is a small mercy, but the catastrophically low pass rate tells you these cars are fundamentally worn out or poorly maintained by this age.
At an average mileage of around 67,000 miles, these 33-year-old survivors are actually running low overall, yet they're still failing MOTs at a rate that suggests systemic mechanical decay rather than high-mileage wear. The zero recorded failures and advisories in the dataset is anomalous and likely reflects incomplete testing data rather than genuine condition. Do not buy one of these cars expecting to keep it on the road without substantial investment in repairs.
We have 1,540 1991 Vauxhall Cavalier Gsi 16v vehicles on record but don't have enough MOT test data to show reliable statistics for this cohort.
What to check before buying a 1991 Vauxhall Cavalier Gsi 16v
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
