2003 Piaggio Vespa Et4

CarHunch analysed 336 real MOT records for the 2003 Piaggio Vespa Et4. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2003 Vespa ET4 is a reliability outlier—just 26.8% pass their MOT first time, barely a third of the UK average of 80%. This isn't a safety crisis (only 3.9% have ever recorded dangerous defects), but it signals these scooters demand consistent maintenance to stay roadworthy.

With a median mileage of only 8,519 miles at test, these Vespas are genuinely low-use vehicles, yet they're still failing regularly, suggesting age and storage conditions matter more than riding miles. The average vehicle accumulates 0.32 failures and 0.5 advisories per test, pointing to wear on exhaust systems, lights, and brakes—typical for 20-year-old scooters. If you're buying one, budget for a pre-purchase inspection by a specialist and assume you'll need work before it passes its next MOT.

What to check before buying a 2003 Piaggio Vespa Et4

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.
