About the 2015 DETHLEFFS UNCLASSIFIED
The 2015 DETHLEFFS UNCLASSIFIED is a large car with a 3000cc diesel engine. 30 of these vehicles were MOT tested in 2024, making it a rare model on UK roads. It sits in the bottom 99% of 2015 cars for MOT pass rates.
With an average of 25,414 miles at 9 years old, DETHLEFFS UNCLASSIFIED owners tend to use this car less than the typical driver. Very low mileage could mean the car has been garaged or used only for short trips, which can cause its own issues like battery drain and moisture buildup.
2015 DETHLEFFS UNCLASSIFIED Fuel Costs
The 3000cc diesel engine is on the larger side, so fuel won't be this car's strong point. Expect around 40 mpg in mixed driving, which works out to roughly £1,245 per year at current diesel prices of 148p per litre (based on 7,400 miles per year). Diesel cars of this age should have their DPF (diesel particulate filter) checked, as replacements can be costly.
