Vauxhall Astra (2003)
2003 Vauxhall Astra
CarHunch analysed 103,827 real MOT records for the 2003 Vauxhall Astra. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2003 Vauxhall Astra is noticeably less reliable than the UK average, with a first-time pass rate of just 71.6% against the national 80%, and a concerning 30.6% of cars having experienced a dangerous defect at some point. Petrol versions fare marginally better at 72.2% pass rate versus 69.9% for diesels, but neither inspires confidence.
At around 67,000 miles median mileage for a 21-year-old car, these Astras are running at reasonable wear levels, yet the average of 4.7 failures and nearly 22 advisories per test suggests persistent mechanical issues rather than isolated problems. Before committing to one, get a pre-purchase inspection focusing on suspension, brakes, and electrical gremlins—the high failure count indicates this isn't a car to buy on hope alone.
Petrol vs Diesel
Pass rate difference of 2.3 percentage points — worth knowing if you're choosing between the two.
What to check before buying a 2003 Vauxhall Astra
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- ⚠️ 30.7% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
