About the 2001 JAGUAR XJ
The 2001 JAGUAR XJ is a premium with a 4cc petrol engine. 972 of these vehicles were MOT tested in 2026, making it a less common model in the UK market. It ranks in the top 25% of all 2001 cars for reliability.
With an average of 91,862 miles at 25 years old, JAGUAR XJ 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.
2001 JAGUAR XJ Fuel Costs
The modest 4cc petrol engine keeps fuel costs low, which is a real advantage for a premium. 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 2001 JAGUAR XJ?
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 79% pass rate. Keeping on top of servicing will help avoid surprises.
JAGUAR XJ Reliability Trend
Newer JAGUAR XJs show better MOT pass rates than older ones, with an average improvement of 7 percentage points.
Buying a Used 2001 JAGUAR XJ
At 25 years old, the JAGUAR XJ 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 94%.
Common Issues to Watch For
Based on the 2001 JAGUAR XJ'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 92k 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.
