About the 2001 Mazda Demio

The 2001 Mazda Demio is a small family car. Our records list a 1498cc petrol engine, though engines vary between versions. 198 MOT tests were recorded on this model in 2024, making it a rare model on UK roads. Among all models from 2001, the average MOT pass rate is 73%, and this model matches that benchmark.

With an average of 66,850 miles recorded at its 2024 MOT tests, Mazda Demio 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.

2001 Mazda Demio Fuel Costs

The 1498cc petrol engine offers a reasonable balance between performance and economy. Expect around 42 mpg in mixed driving, which works out to roughly £1,398 per year with petrol at 174.57p per litre (GOV.UK weekly average, week of 19 October 2026; based on 7,400 miles per year).

What does it cost to own a 2001 Mazda Demio?

Total estimated annual running cost is £2,228 (£186/month), broken down as £1,398 fuel, £275 road tax, £55 MOT, and £500 predicted repairs. Repair costs are moderate, reflecting the 73% pass rate. Keeping on top of servicing will help avoid surprises.

Buying a Used 2001 Mazda Demio

At 25 years old, the Mazda Demio is firmly in budget territory. Purchase prices are low, but check for rust, worn suspension bushes, and electrical gremlins. A full service history is especially valuable at this age. If you're flexible on year, the 2000 model has the highest pass rate at 75%.

Common Issues to Watch For

These are typical issues for cars of this age, fuel type and engine size, not faults recorded on this model's MOT tests. Use them as a checklist when you view one.

Rust and Corrosion

Watch out

At 10+ years, check wheel arches, sills, subframe, and brake lines for rust. Structural corrosion is an MOT failure. Prevention is far cheaper than repair.

Suspension Bushings

Watch out

Rubber suspension bushes harden and crack with age, causing knocking noises and vague handling. A full refresh costs £300-£800 depending on the car.

Service History

Low risk

Always request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
