The 2020 Vauxhall Insignia passes its first MOT at 86.7%, comfortably above the UK average of 80%, which is a solid result for a four-year-old model. However, 18.4% of vehicles in this cohort have experienced a dangerous defect at some point—approaching the threshold where buyers should factor in extra caution during inspections and test drives.
At a median mileage of 48,664 miles, these Insignias are running fairly hard for their age, yet they're generating just 0.47 failures per vehicle on average, suggesting the mechanical fundamentals hold up reasonably well. Most issues appear minor: advisories average 2.7 per car and are likely wear-and-tear items rather than structural problems. Before purchasing, have any prospective Insignia inspected by a trusted mechanic who can specifically check the braking system and suspension, as these often appear in the advisory logs.
The 2020 Vauxhall Insignia passes its MOT first time at roughly the UK average rate (88.9%) — solid but worth checking this vehicle's history carefully.
These stats describe 1,192 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
