Advice for buyers
What should I look for in a used Jaguar XK sports?
There's plenty to go wrong and you should expect it to. According to the What Car?/Warranty Direct Reliability Index, Jaguars aren't reliable and are costly to fix. Watch that hood in particular. If the motor fails or the fabric tears, repairs will cost a mint.
Older engines can suffer bore wear - watch for misfires and exhaust smoke as you blip the throttle. Timing chain rattles also need some investigation because a relatively cheap repair to the tensioner can prevent a much dearer engine rebuild.
