In the believe it or not category, but a visit to the Jaguar forum might be convincing; most of the problems people are having with their 15-25 year old Jaguars comes from letting them sit unused. The daily driver crowd, like me, have the fewest issues. One of the main problems after sitting for a while is the fuel pump seizing up. And in some models getting to the fuel pump takes an act of congress.
Aside from that, cam chain tensioners in the V-8’s made from 1998-2002 were the #1 boogie-man. Those cars have mostly been crashed, retired or fixed by now.
