2004 Smart Roadster Speedsilver Auto
CarHunch analysed 128 real MOT records for the 2004 Smart Roadster Speedsilver Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2004 SMART ROADSTER SPEEDSILVER AUTO falls below the UK average pass rate at 74.9% versus 80%, which is a meaningful gap—but the real concern is that 35.2% of these cars have suffered dangerous defects, well above the typical threshold. This is a reliability red flag that should weigh heavily in your purchase decision.
At 53,447 miles average and 50,495 miles median, these Roadsters are reasonably low-mileage for their age, yet they're still generating 4.19 failures and 21.6 advisories per vehicle on average, suggesting the model has genuine wear-and-tear vulnerabilities. Before committing to one, get a pre-purchase inspection that specifically covers suspension, braking, and electrical systems—the clusters most likely to trip the dangerous defect rating.
What to check before buying a 2004 Smart Roadster Speedsilver Auto
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.
- ⚠️ 35.2% 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.
