About the 2002 JAGUAR XK8
The 2002 JAGUAR XK8 is a premium performance with a 4196cc petrol engine. 1,199 of these vehicles were MOT tested in 2026, making it a reasonably common sight on UK roads. Among all cars from 2002, the average MOT pass rate is 73%, and this model beats that benchmark.
With an average of 84,611 miles at 24 years old, JAGUAR XK8 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.
2002 JAGUAR XK8 Fuel Costs
The 4196cc 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 2002 JAGUAR XK8?
Total estimated annual running cost is £2,907 (£242/month), broken down as £1592 fuel, £760 road tax, £55 MOT, and £500 predicted repairs. Repair costs are moderate, reflecting the 76% pass rate. Keeping on top of servicing will help avoid surprises.

Buying a Used 2002 JAGUAR XK8
At 24 years old, the JAGUAR XK8 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 2005 model has the highest pass rate at 84%.
Common Issues to Watch For
Based on the 2002 JAGUAR XK8's fuel type, age, and engine size, these are the most likely problem areas to check.
Timing Chain / Belt
Watch outAt 24 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 riskLarger 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 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 85k 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.
