Wrightbus Streetdeck 4dc (2018)
2018 Wrightbus Streetdeck 4dc
CarHunch analysed 139 real MOT records for the 2018 Wrightbus Streetdeck 4dc. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2018 Wrightbus Streetdeck 4DC has a first-time MOT pass rate of just 19.7%, catastrophically below the UK average of 80%, though the silver lining is that zero vehicles in this cohort have recorded dangerous defects. The diesel-only fleet (137 of 139 vehicles) passes at 18.5%, suggesting the issue is systematic to the model rather than fuel type.
These are buses with average mileage of 108,985 miles at six years old—relatively high usage, typical for commercial operation—yet the average of only 0.04 failures per vehicle suggests most don't fail on substantive safety grounds; instead, they're likely failing on minor or procedural compliance items endemic to the MOT testing of large vehicles. If you're considering purchasing one, inspect maintenance records meticulously and budget for pre-test remedial work, as the pass rate points to either poor upkeep across the fleet or recurring minor defects that require addressing before each test.
What to check before buying a 2018 Wrightbus Streetdeck 4dc
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.
