Rover Sterling (1991)
1991 Rover Sterling
CarHunch analysed 200 real MOT records for the 1991 Rover Sterling. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 1991 Rover Sterling has a first-time MOT pass rate of just 9.9%, less than one-eighth of the UK average of 80%, making it one of the most unreliable vehicles of its generation. Dangerous defects are uncommon at 1.5%, but the sheer scale of mechanical problems—averaging 0.21 failures and 0.7 advisories per vehicle—signals deep structural issues that compound with age.
At 100,672 miles median mileage, these cars have covered typical distance for their 33-year lifespan, yet are falling apart at the MOT bay rather than showing graceful ageing. If you're considering one, accept that you're buying a project requiring immediate work, not a usable classic: budget for multiple repairs before it will pass its next test.
What to check before buying a 1991 Rover Sterling
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.
