Mitsubishi Sigma (1994)
1994 Mitsubishi Sigma
CarHunch analysed 121 real MOT records for the 1994 Mitsubishi Sigma. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 1994 Mitsubishi Sigma arrives at MOT with a 68% first-time pass rate—12 percentage points below the UK average of 80%—suggesting these 30-year-old cars need closer mechanical attention than typical vehicles of this age. The good news is that only 13.2% have ever had a dangerous defect recorded, so safety failures aren't endemic, but the average 1.6 failures per test signals consistent wear issues you'll want budgeted for.
These Sigmas are running at a median of 116,000 miles, which is reasonable for their age, yet they're still averaging 6.2 advisories each—a sign that minor systems and consumables are degrading faster than you'd hope. If you're considering one, get a full pre-purchase inspection focused on brake and suspension components, since the pattern of frequent small faults suggests neglect elsewhere is likely too.
What to check before buying a 1994 Mitsubishi Sigma
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.
