1999 Mercedes 208d Swb

CarHunch analysed 141 real MOT records for the 1999 Mercedes 208d Swb. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 1999 Mercedes 208D SWB is a genuinely unreliable proposition: only 16.6% pass first time against the UK average of 80%, making it a vehicle you'd expect to fail its MOT and require repairs before it can be driven legally. The dangerous defect rate of 5.7% is mercifully below the serious-concern threshold, but the median CarHunch score of 55 reflects a fundamentally tired model.

At 146,900 miles median mileage, these vans are well-used workhorses, yet they're still accumulating 0.57 failures and 1.4 advisories per test—suggesting chronic wear rather than a few fixable problems. Before buying one, get a full pre-purchase inspection focusing on the engine bay and cooling system, because the failure patterns on this cohort suggest you'll be spending money on repairs regularly.

What to check before buying a 1999 Mercedes 208d Swb

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.
