2003 Suzuki Grand Vitara

CarHunch analysed 7,361 real MOT records for the 2003 Suzuki Grand Vitara. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2003 Grand Vitara falls slightly below the UK average with a 77.9% first-time pass rate, and nearly 28% of these vehicles have recorded dangerous defects—a meaningful concern for any buyer. Petrol versions perform marginally better at 78.4% versus 76.4% for diesel, though neither is a standout figure.

At just over 64,000 miles median mileage for a 21-year-old car, these are relatively low-mileage examples, which explains why they average nearly 4 failures per test—age-related wear rather than heavy use. With 23 advisories per vehicle on average, expect a long list of minor niggles; before buying, get a pre-purchase inspection focused on suspension, brakes, and fluid leaks, as these older Suzukis tend to accumulate exactly those issues.

What to check before buying a 2003 Suzuki Grand Vitara

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.
  • ⚠️ 27.6% 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.
