I liked the V12 in my old XKE.... That was a smooth engine.
Sometimes wish I still had it...
Those old Jags are nice, but if I were going to buy one with the stock engine I'd be already satisfied with the XJ fitted with an inline-6. It's an old design, but still reported to be one of the best gassers ever made...
