How many miles will a 1998 XJ8 last?
The 48 mileages owners gave run from 65 to 150,786 miles. A quarter are at or under 54,000 miles, half at or under 69,000, three quarters at or under 100,000 and nine in ten at or under 121,000; 11 (23%) came after 100,000 miles, 1 (2%) after 150,000 and none after 200,000.
These mileages say when owners reported a problem, not when a 1998 XJ8 wears out. NHTSA's file holds only vehicles whose owners complained; one that ran without a problem never appears in it, so it gives no lifespan and no cutoff, and how a vehicle was maintained matters more than any one odometer reading.
Most of these reports came early in the vehicle's life: 37 of the 48 came at or under 100,000 miles. The 11 past that mark show the 1998 XJ8 still being driven at those mileages, not how many reach them: NHTSA's file counts complaints, not the vehicles on the road.

Is the 1998 XJ8 a good year?
Complaint counts cannot say whether the 1998 is a good or a bad XJ8: they rise with how many were sold and how long they have been on the road. They show how the 1998 compares with the other model years in NHTSA's file.
With 83 complaints, the 1998 drew the most of the 4 Jaguar XJ8 model years from 1998 to 2004 with 10 or more complaints. The fewest: the 1999 (11).
Recent model years have had less time to collect complaints, so their counts are still growing. No year is ranked by mileage here, because a year's median mileage mostly follows its age.

What these figures can and cannot tell you
- Complaints are owners’ reports to NHTSA. NHTSA publishes them without verifying them: a complaint is an allegation, not a defect finding.
- The mileage is what the owner wrote on the complaint; NHTSA does not check it against the odometer.
- The make, model and model year are the ones on the complaint. NHTSA records them as filed, so a few complaints sit under a model year the name was not sold in.
- They are not a lifespan study. The file holds only vehicles whose owners reported a problem, so these figures do not say how long a typical 1998 XJ8 lasts.
- A complaint count rises with how many vehicles were sold and how long they have been on the road, so it is not a rating of the 1998 XJ8.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 35 of the 83 complaints on the 1998 Jaguar XJ8 give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every mileage figure.
- NHTSA name counted: XJ8. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only this one.
- Recall-file name matched: XJ8.
