- What is the GVRI for the Porsche Boxster?
- The Porsche Boxster has a Gera Vehicle Risk Index (GVRI) of 25/100 (Low Risk), computed from 31,420 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 Porsche Boxster?
- The Porsche Boxster MOT fail rate is 16.9% based on 31,420 class-4 normal MOT tests recorded by DVSA in 2016. This means 16.9% of tests resulted in a 'Fail' outcome. The UK class-4 normal test fail rate across the fleet is 25.0%.
- Is the Porsche Boxster a high-risk car to insure?
- The GVRI of 25/100 places the Porsche Boxster in the Low Risk band, below 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.
