About the 1991 MAZDA RX-7

The 1991 MAZDA RX-7 is a large car with a 2616cc petrol engine. 34 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. Among all cars from 1991, the average MOT pass rate is 78%, and this model beats that benchmark.

With an average of 70,478 miles at 35 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.

1991 MAZDA RX-7 Fuel Costs

The 2616cc petrol engine is on the larger side, so fuel won't be this car's strong point. Expect around 30 mpg in mixed driving, which works out to roughly £1,592 per year at current petrol prices of 142p per litre (based on 7,400 miles per year).

What does it cost to own a 1991 MAZDA RX-7?

Total estimated annual running cost is £2,427 (£202/month), broken down as £1592 fuel, £430 road tax, £55 MOT, and £350 predicted repairs. Repair costs are moderate, reflecting the 82% pass rate. Keeping on top of servicing will help avoid surprises.

MAZDA RX-7 Reliability Trend

Buying a Used 1991 MAZDA RX-7

At 35 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 34 tests in our data, these figures should be treated as indicative rather than definitive.

Common Issues to Watch For

Based on the 1991 MAZDA RX-7's fuel type, age, and engine size, these are the most likely problem areas to check.

Timing Chain / Belt

Watch out

At 35 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.

Oil Consumption

Medium risk

Larger petrol engines can develop higher oil consumption as they age. Check the oil level and look for blue smoke from the exhaust.

Rust and Corrosion

Watch out

At 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 out

Rubber 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 risk

Always request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
