- What is the GVRI for the Mg Zt?
- The Mg Zt has a Gera Vehicle Risk Index (GVRI) of 57/100 (High Risk), computed from 6,562 DVSA Anonymised MOT class-4 (car) normal tests in 2016. The UK fleet average GVRI is 37/100. A GVRI of 0 = lowest risk; 100 = highest.
- What is the MOT fail rate for the Mg Zt?
- The Mg Zt MOT fail rate is 40.2% based on 6,562 class-4 normal MOT tests recorded by DVSA in 2016. This means 40.2% of tests resulted in a 'Fail' outcome. The UK class-4 normal test fail rate across the fleet is 25.0%.
- Is the Mg Zt a high-risk car to insure?
- The GVRI of 57/100 places the Mg Zt in the High Risk band, above the UK fleet average of 37/100. Higher GVRI means higher mechanical defect risk from real MOT data, which correlates with claim risk. However, insurance premiums also depend on driver profile, postcode, NCB, annual mileage, and policy type — the GVRI is one indicator, not a premium quote.
- How is the Gera Vehicle Risk Index calculated?
- GVRI = 0.6 × MOT_fail_rate + 0.4 × avg_defect_severity_norm, min-max scaled 0–100. MOT fail rate = failed tests ÷ total class-4 normal tests. Defect severity = mean severity of 'F' items per failed test (1 = standard failure, 3 = dangerous item). Full methodology on the GVRI methodology page. Source: DVSA 2016 data, OGL v3.0.
