About the 1999 MAZDA DEMIO
The 1999 MAZDA DEMIO is a small family car with a 1323cc petrol engine. 231 of these vehicles were MOT tested in 2026, making it a less common model in the UK market. Among all cars from 1999, the average MOT pass rate is 75%, and this model falls short of that benchmark.
With an average of 78,427 miles at 27 years old, 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.
1999 MAZDA DEMIO Fuel Costs
The 1323cc petrol engine offers a reasonable balance between performance and economy. Expect around 42 mpg in mixed driving, which works out to roughly £1,137 per year at current petrol prices of 142p per litre (based on 7,400 miles per year).
What does it cost to own a 1999 MAZDA DEMIO?

Buying a Used 1999 MAZDA DEMIO
At 27 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 1998 model has the highest pass rate at 76%.
Common Issues to Watch For
Based on the 1999 MAZDA DEMIO's fuel type, age, and engine size, these are the most likely problem areas to check.
Rust and Corrosion
Watch outAt 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 outRubber 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 riskAlways request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
