That Jag S 4ltr was a lovely car and could be driven like a sports car, and I did. The only issue I had was overheating which as I remember was a known problem and had three possible known common causes, mine being a split plastic tube from the water reservoir.
I was sad to see it go but I wanted another soft top. I sold it to a guy who owned a trucking company and a bit later I just happened to spot that car on Autotrader with fewer miles on the clock than it had when I owned it. Funny That.
I wont be throwing any RR/LR 4x4 about like a sports car or getting anywhere near top speed so the engine size is pretty irrelevant except whatever I may get will be petrol, not diesel.
