About the 1990 MAZDA EUNOS
The 1990 MAZDA EUNOS is a small family car with a 1600cc petrol engine. 47 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. It ranks in the top 13% of all 1990 cars for reliability.
With an average of 93,777 miles at 36 years old, MAZDA EUNOS 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.
1990 MAZDA EUNOS Fuel Costs
The 1600cc 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 1990 MAZDA EUNOS?

Buying a Used 1990 MAZDA EUNOS
At 36 years old, the MAZDA EUNOS 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 1991 model has the highest pass rate at 91%. Note: with only 47 tests in our data, these figures should be treated as indicative rather than definitive.
Common Issues to Watch For
Based on the 1990 MAZDA EUNOS's fuel type, age, and engine size, these are the most likely problem areas to check.
Timing Chain / Belt
Watch outAt 36 years old, check whether the timing belt has been replaced (typically due every 5-7 years or 60,000-100,000 miles). A snapped belt can destroy the engine.
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.
Clutch Wear
Medium riskWith an average of 94k miles, clutch replacement may be due (typical lifespan 60,000-100,000 miles). Budget £400-£800 for a new clutch kit.
Brake Discs and Pads
Medium riskHigh-mileage cars often need brake disc replacement, not just pads. A full set of discs and pads costs £200-£500 per axle.
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.
