About the 1992 Jaguar XJS

The 1992 Jaguar XJS is a premium performance car. Our records list a 4000cc petrol engine, though engines vary between versions. 618 MOT tests were recorded on this model in 2024, making it a less common model in the UK market. Among all models from 1992, the average MOT pass rate is 77%, and this model beats that benchmark.

With an average of 89,147 miles recorded at its 2024 MOT tests, Jaguar XJS 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.

1992 Jaguar XJS Fuel Costs

The 4000cc 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 1992 Jaguar XJS?

Total estimated annual running cost is £2,888 (£241/month), broken down as £1,958 fuel, £375 road tax, £55 MOT, and £500 predicted repairs. Repair costs are moderate, reflecting the 78% pass rate. Keeping on top of servicing will help avoid surprises.

Jaguar XJS Reliability Trend

Newer Jaguar XJSs pass their MOT more often than older ones, by 4 percentage points on average, which is mostly down to age and wear.

Buying a Used 1992 Jaguar XJS

At 34 years old, the Jaguar XJS 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 34 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.

Clutch Wear

Medium risk

With an average of 89k 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 risk

High-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 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.
