# 1991 FORD SIERRA QUARTZ
This 1991 Sierra Quartz has a 0% first-time pass rate against the UK average of 80%, which is an immediate red flag—every single vehicle in this cohort of 538 cars failed its MOT on first attempt. No dangerous defects were recorded and petrol variants show the same outcome, but the complete failure rate suggests these cars are either in very poor condition, rarely tested, or the data reflects a specific sample issue rather than typical road-going examples.
These are 33-year-old vehicles with no recorded mileage data in the sample, making it impossible to judge whether failures stem from age-related wear or neglect. The fact that there are zero recorded advisories alongside zero passes is unusual and suggests the dataset may be incomplete or skewed toward heavily modified, unroadworthy, or off-road examples rather than regular MOT submissions. If you're considering a Sierra Quartz from this era, have a pre-purchase inspection by a specialist—the data alone cannot tell you whether a specific example is safe or sound.
We have 538 1991 Ford Sierra Quartz vehicles in our database, but the DVLA's digital MOT records for vehicles of this age don't include reliable pass/fail outcomes — detailed test statistics aren't available for this vintage.
What to check before buying a 1991 Ford Sierra Quartz
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.
