Got a specific Mercedes 300d Diesel Auto 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.
The 1991 Mercedes 300D diesel auto achieves an 83.5% first-time MOT pass rate across 158 vehicles, slightly above the UK average of 80%, with no recorded dangerous defects in the cohort. This is a genuinely clean safety record for a 33-year-old luxury saloon, and the negligible failure rate (0.04 failures per vehicle) speaks to the model's engineering durability.
These cars are running at a median mileage of 187,297 miles—well-used examples, but typical for a model that was built to last and often cherished by long-term owners. The lack of advisories suggests that survivors in this age bracket have either been well-maintained or are past the point where minor wear items trigger repeatable warnings. If you're considering one, get a pre-purchase inspection that focuses on transmission fluid condition, cooling system integrity, and suspension bushes, as these are the areas that tend to matter most on older Mercedes when MOT records alone can't tell the full story.
We have 158 1991 Mercedes 300d Diesel Auto 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
