Which year to buy? →
The 2020 Vauxhall Astra is a reliably built car, with a first-time MOT pass rate of 90.4% — well ahead of the UK average of 80%. Only 12.6% of vehicles have ever recorded a dangerous defect, which is reassuringly low and suggests no systemic safety concerns.
At just under 25,000 miles median, these cars are relatively young and lightly used, which partly explains the strong pass rate. The average vehicle has accumulated only 0.4 failures and 2.5 advisories, pointing to straightforward maintenance needs rather than serious mechanical problems — if you're buying one, have a pre-purchase inspection focus on wear items like brakes and suspension rather than expecting major engine or gearbox issues.
The 2020 Vauxhall Astra passes its MOT first time more often than most UK vehicles (91% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
These stats describe 2,379 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.

Brake pipes, sills and subframes are the key areas on a vehicle this age — structural rust is hard to spot without getting underneath. A mechanic will check all of this before you commit, and give you a concrete basis to negotiate on price.
