What should I look for in a used Jaguar XJ saloon?
It's vital to buy a car with a service history, as there have been a number of recalls. 1998 XJs had problems with throttles not opening properly, and some 1999 cars had transmission glitches that caused them to lock up.
You should also check - or get someone else to check - that the throttle is not fouling the underbonnet liner and that the power steering pipe is not chafing the alternator terminals. Be aware that the front suspension bushes need replacing every 25,000 miles and, on an XJR, make sure the brakes are in good order.
Despite all that - and, you'd be forgiven for having second thoughts about the big Jag - XJs have actually proved generally pretty sound an reliable. In a recent JD Power survey, Jaguar was the top British marque, and it fared well in the Warranty Direct reliability league
