About the 2003 MERCEDES HYMER
The 2003 MERCEDES HYMER is a city car with a 27cc diesel engine. 49 of these vehicles were MOT tested in 2024, making it a rare model on UK roads. It ranks in the top 6% of all 2003 cars for reliability.
With an average of 67,183 miles at 21 years old, MERCEDES HYMER 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.
2003 MERCEDES HYMER Fuel Costs
The modest 27cc diesel engine keeps fuel costs low, which is a real advantage for a city car. Expect around 55 mpg in mixed driving, which works out to roughly £905 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.
What does it cost to own a 2003 MERCEDES HYMER?
Total estimated annual running cost is £1,190 (£99/month), broken down as £905 fuel, £30 road tax, £55 MOT, and £200 predicted repairs. The low repair estimate reflects the excellent 90% pass rate. These cars rarely fail their MOT, so unexpected bills are less likely.
