Polaris Unknown (2005)
2005 Polaris Unknown
CarHunch analysed 146 real MOT records for the 2005 Polaris Unknown. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2005 Polaris is a reliability disaster by MOT standards—just 2.7% of vehicles pass first time, compared to the UK average of 80%. The dangerous defect rate of 1.4% is low, but that's cold comfort when nearly 97% of these machines fail their initial test.
The extremely low mileage (762 miles median) suggests these are either barely-used vehicles or the MOT data covers a niche market segment, making typical wear-and-tear comparisons unreliable. With an average of 0.06 failures per vehicle and only 0.2 advisories, the issue isn't quantity of problems but severity—something fundamental is consistently broken on first test. If you're seriously considering one, budget for immediate rectification work before it's roadworthy.
What to check before buying a 2005 Polaris Unknown
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.
