The 1998 Jaguar XK8 passes its MOT first time in only 75.6% of cases, which is 4.4 percentage points below the UK average—a modest but telling gap that reflects the age and complexity of this model. More concerning is that 35.2% of these cars have recorded a dangerous defect at some point, which is well above typical levels and should give any buyer serious pause.

At just over 82,000 miles median mileage, these XK8s have covered reasonable ground for their age, yet they're accumulating an average of 4.5 failures and nearly 28 advisories per test—indicating that wear and deferred maintenance are real issues. Before viewing any example, get a pre-purchase inspection focused on the cooling system and electrical gremlins that plague this generation, and budget for likely MOT work.

The 1998 Jaguar Xk8 has a decent first-time pass rate (75.6%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context
🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.
🔧 Expect consumable spend. An average of 27.7 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.
🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 2,190 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
