Reliant Rialto (1989)
1989 Reliant Rialto
CarHunch analysed 476 real MOT records for the 1989 Reliant Rialto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 1989 Reliant Rialto passes its MOT first time in 73.5% of cases—notably below the UK average of 80%—which suggests these cars are more prone to developing faults than most vehicles of their age. With 16.8% of tested examples having recorded a dangerous defect at some point, buyers need to factor in the cost of remedial work before purchase.
At nearly 57,000 miles on average, these Rialtos show typical mileage for their age, but they're averaging 2.14 failures and 3.7 advisories per test, indicating persistent mechanical issues rather than isolated problems. Before buying, get a pre-purchase inspection that specifically covers the brake and suspension systems, where most failures cluster on this model.
What to check before buying a 1989 Reliant Rialto
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.
