About the 2006 MAZDA RX-7
The 2006 MAZDA RX-7 is a small family car with a 1300cc petrol engine. 36 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. Among all cars from 2006, the average MOT pass rate is 73%, and this model beats that benchmark.
With an average of 65,339 miles at 20 years old, MAZDA RX-7 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.
2006 MAZDA RX-7 Fuel Costs
The 1300cc 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).

Buying a Used 2006 MAZDA RX-7
At 20 years old, the MAZDA RX-7 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 2003 model has the highest pass rate at 97%. Note: with only 36 tests in our data, these figures should be treated as indicative rather than definitive.
Common Issues to Watch For
Based on the 2006 MAZDA RX-7'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.
