About the 1991 Honda NSX

The 1991 Honda NSX is a large car. Our records list a 2970cc petrol engine, though engines vary between versions. 141 MOT tests were recorded on this model in 2024, making it a rare model on UK roads. It ranks in the top 4% of all 1991 models for MOT pass rate.

With an average of 68,904 miles recorded at its 2024 MOT tests, Honda NSX 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 Honda NSX Fuel Costs

The 2970cc 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 £1,958 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 Honda NSX?

Total estimated annual running cost is £2,588 (£216/month), broken down as £1,958 fuel, £375 road tax, £55 MOT, and £200 predicted repairs. The low repair estimate reflects the excellent 99% pass rate. These cars rarely fail their MOT, so unexpected bills are less likely.

Buying a Used 1991 Honda NSX

At 35 years old, the Honda NSX 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.

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.

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.
