MG Zr (2002)
2002 MG Zr
CarHunch analysed 12,337 real MOT records for the 2002 MG Zr. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2002 MG ZR falls well short of the UK average with a 69.8% first-time pass rate, meaning nearly a third of these cars fail their MOT—and one in five has suffered a dangerous defect, a genuine safety concern for buyers. Petrol and diesel variants perform almost identically, both around 70%, so fuel type won't be a deciding factor in reliability.
These ZRs are averaging 62,858 miles—reasonable for a 22-year-old car—but they're racking up 3.4 failures and 9.3 advisories per vehicle, signalling widespread wear across multiple systems rather than one weak spot. Budget for repairs and have any ZR you're considering given a thorough pre-purchase inspection, because the numbers suggest these cars require consistent maintenance to stay roadworthy.
What to check before buying a 2002 MG Zr
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.
- ⚠️ 20.8% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
