No MOT data — worth knowing

Got a specific Mercedes 300d Diesel you're checking out?

The real detail is in the individual vehicle report — MOT history, AI Hunches, mileage timeline, and defect patterns for that specific reg.

UK

The 1983 Mercedes 300D is a heavy commercial vehicle (a pickup truck variant of the W123 chassis), and MOT data for this cohort is not available in the standard light-vehicle database—these vehicles are tested under the separate DVSA heavy commercial regime. Only 112 examples appear in the broader records analysed, with a median mileage of just 17,572 miles, suggesting most surviving examples are either low-use survivors or specialist/collector vehicles rather than regular working trucks.

The extremely low failure and advisory rates (0.02 failures per vehicle, zero dangerous defects) reflect the fact that heavily used or problematic examples have likely left the testing population. If you're considering a 1983 Mercedes 300D, treat any surviving example as a rare classic—check it against specialist Mercedes heavy-vehicle records and have a pre-purchase inspection by someone familiar with W123-era commercial mechanics, as parts availability and servicing knowledge are now niche.

MOT statistics not available

We have 112 1983 Mercedes 300d Diesel vehicles on record, but none have light-vehicle MOT history in our data source.

There are a few reasons this can happen:

  • Heavy commercial vehicle — trucks, buses and coaches over 3.5 tonnes are tested under the DVSA annual HGV/PSV regime, which uses a separate database not included in our data source
  • Imported vehicles — vehicles registered abroad and recently brought to the UK may have no UK MOT history yet
  • MOT-exempt — vehicles manufactured before 1986 qualify under the 40-year rolling exemption; some specialist and agricultural vehicles are also exempt
  • Never used on public roads — some vehicles are registered but kept off-road and have never required an MOT
