Vauxhall Astra Sxi Cdti 100 (2005)
2005 Vauxhall Astra Sxi Cdti 100
CarHunch analysed 166 real MOT records for the 2005 Vauxhall Astra Sxi Cdti 100. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2005 Astra diesel is substantially less reliable than the UK average—only 56.3% pass first time compared to 80% nationally—which means you're looking at a one-in-two chance of an MOT failure on any given year. The good news is that dangerous defects are rare (0%), so when things do fail, they're typically fixable rather than safety-critical.
At 146,753 miles median, these Astras have genuine age-related wear, and the 0.67 average failures per vehicle suggests structural or mechanical issues beyond simple consumables. Before committing to one, get a pre-purchase inspection focused on the diesel engine, suspension, and brakes—this cohort's track record shows you'll be paying for repairs regularly if you don't buy a mechanically sound example.
What to check before buying a 2005 Vauxhall Astra Sxi Cdti 100
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.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
