About the 1991 Rover Mini

The 1991 Rover Mini is a small family car. Our records list a 1275cc petrol engine, though engines vary between versions. 2,744 MOT tests were recorded on this model in 2024, making it a reasonably common sight on UK roads. Among all models from 1991, the average MOT pass rate is 79%, and this model beats that benchmark.

With an average of 50,719 miles recorded at its 2024 MOT tests, Rover Mini 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 Rover Mini Fuel Costs

The 1275cc petrol engine offers a reasonable balance between performance and economy. Expect around 42 mpg in mixed driving, which works out to roughly £1,398 per year with petrol at 174.57p per litre (GOV.UK weekly average, week of 19 October 2026; based on 7,400 miles per year).

What does it cost to own a 1991 Rover Mini?

Total estimated annual running cost is £2,033 (£169/month), broken down as £1,398 fuel, £230 road tax, £55 MOT, and £350 predicted repairs. Repair costs are moderate, reflecting the 80% pass rate. Keeping on top of servicing will help avoid surprises.

The Rover Mini has maintained consistent MOT pass rates across model years, varying by only 2 percentage points.

Buying a Used 1991 Rover Mini

At 35 years old, the Rover Mini 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 1990 model has the highest pass rate at 80%.

Common Issues to Watch For

These are typical issues for cars of this age, fuel type and engine size, not faults recorded on this model's MOT tests. Use them as a checklist when you view one.

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.
