About the 2012 MAZDA MX5
The 2012 MAZDA MX5 is a family car with a 1789cc petrol engine. 50 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. Among all cars from 2012, the average MOT pass rate is 78%, and this model beats that benchmark.
With an average of 35,968 miles at 14 years old, MAZDA MX5 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.
2012 MAZDA MX5 Fuel Costs
The 1789cc petrol engine offers a reasonable balance between performance and economy. Expect around 36 mpg in mixed driving, which works out to roughly £1,327 per year at current petrol prices of 142p per litre (based on 7,400 miles per year).
What does it cost to own a 2012 MAZDA MX5?
Total estimated annual running cost is £2,047 (£171/month), broken down as £1327 fuel, £315 road tax, £55 MOT, and £350 predicted repairs. Repair costs are moderate, reflecting the 86% pass rate. Keeping on top of servicing will help avoid surprises.
Buying a Used 2012 MAZDA MX5
At 14 years old, the MAZDA MX5 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 50 tests in our data, these figures should be treated as indicative rather than definitive.
Common Issues to Watch For
Based on the 2012 MAZDA MX5's fuel type, age, and engine size, these are the most likely problem areas to check.
Timing Chain / Belt
Watch outAt 14 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.
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.
