About the 1991 NISSAN UNCLASSIFIED
The 1991 NISSAN UNCLASSIFIED is a city car with a 980cc petrol engine. 121 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 falls short of that benchmark.
With an average of 83,984 miles at 35 years old, NISSAN UNCLASSIFIED 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 NISSAN UNCLASSIFIED Fuel Costs
The modest 980cc petrol engine keeps fuel costs low, which is a real advantage for a city car. Expect around 50 mpg in mixed driving, which works out to roughly £955 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 NISSAN UNCLASSIFIED?
Total estimated annual running cost is £1,530 (£128/month), broken down as £955 fuel, £20 road tax, £55 MOT, and £500 predicted repairs. Repair costs are moderate, reflecting the 77% pass rate. Keeping on top of servicing will help avoid surprises.
NISSAN UNCLASSIFIED Reliability Trend
Newer NISSAN UNCLASSIFIEDs show better MOT pass rates than older ones, with an average improvement of 4 percentage points.
Buying a Used 1991 NISSAN UNCLASSIFIED
At 35 years old, the NISSAN UNCLASSIFIED 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 2019 model has the highest pass rate at 88%.
Common Issues to Watch For
Based on the 1991 NISSAN UNCLASSIFIED's fuel type, age, and engine size, these are the most likely problem areas to check.
Coil Pack Failure
Medium riskSmaller petrol engines are prone to ignition coil failures, causing misfires and rough running. Replacement is £50-£150 per coil.
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.
Clutch Wear
Medium riskWith an average of 84k miles, clutch replacement may be due (typical lifespan 60,000-100,000 miles). Budget £400-£800 for a new clutch kit.
Brake Discs and Pads
Medium riskHigh-mileage cars often need brake disc replacement, not just pads. A full set of discs and pads costs £200-£500 per axle.
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.
