Seat Inca (2003)
2003 Seat Inca
CarHunch analysed 666 real MOT records for the 2003 Seat Inca. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2003 SEAT INCA is significantly less reliable than the UK average, with a first-time pass rate of just 68% against the national 80%, and over one in three examples (35.9%) have recorded a dangerous defect on file—a serious concern for prospective buyers. These are almost exclusively diesel models, so fuel type isn't a differentiating factor here.
At nearly 90,000 miles median, these vehicles are showing their age, and the data backs that up: the average car fails on 4.8 defects and racks up nearly 20 advisories per test, pointing to widespread wear across suspension, braking, and emissions systems. If you're considering one, budget for immediate work on the advisory items and have a pre-purchase inspection focus on brake and suspension components, which typically dominate the failure list for ageing diesel vans of this era.
What to check before buying a 2003 Seat Inca
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.
- ⚠️ 35.9% 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.
