About the 1990 JAGUAR XJR

The 1990 JAGUAR XJR is a premium performance with a 5993cc petrol engine. 106 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. It ranks in the top 12% of all 1990 cars for reliability.

With an average of 132,962 miles at 36 years old, JAGUAR XJR 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.

1990 JAGUAR XJR Fuel Costs

The 5993cc 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 1990 JAGUAR XJR?

Total estimated annual running cost is £2,757 (£230/month), broken down as £1592 fuel, £760 road tax, £55 MOT, and £350 predicted repairs. Repair costs are moderate, reflecting the 89% pass rate. Keeping on top of servicing will help avoid surprises.

JAGUAR XJR Reliability Trend

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

Buying a Used 1990 JAGUAR XJR

At 36 years old, the JAGUAR XJR 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 1991 model has the highest pass rate at 100%.

Common Issues to Watch For

Based on the 1990 JAGUAR XJR's fuel type, age, and engine size, these are the most likely problem areas to check.

Timing Chain / Belt

Watch out

At 36 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.
