The 2003 Opel Astra falls short of the UK average with a 72.1% first-time pass rate versus 80%, signalling below-average reliability for its age. Nearly a quarter of these vehicles (23.6%) have recorded a dangerous defect at some point, which is a meaningful concern for a buyer considering a 20-year-old example.

These Astras are running at a reasonable 73,149 miles median, but they're racking up an average of 4 failures and nearly 19 advisories per test, suggesting age-related wear is catching up across the board. If you're serious about one, budget for immediate work on suspension, braking, and emissions components—and get a pre-purchase inspection done by someone who knows these cars well.
