About the 1997 MAZDA 121
The 1997 MAZDA 121 is a small family car with a 1242cc petrol engine. 33 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. It ranks in the top 25% of all 1997 cars for reliability.
With an average of 50,567 miles at 29 years old, MAZDA 121 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.
1997 MAZDA 121 Fuel Costs
The 1242cc 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 1997 MAZDA 121?

Buying a Used 1997 MAZDA 121
At 29 years old, the MAZDA 121 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. Note: with only 33 tests in our data, these figures should be treated as indicative rather than definitive.
Common Issues to Watch For
Based on the 1997 MAZDA 121'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.
