Hi

I tried both and decided on a 2.5 (SE not sport, due to the extra toys)
After reading various opinions I wasn't sure that it was worth it after
buying, then it went for it's service and I was loaned a 2.0.
After that I was sure that the 2.5 was much better to drive (maybe it's the
4 wheel drive) but it seems to sit better on the road
and goes a lot better, not just initial acceleration but mid range pickup
for motorway work (which I do a lot of)

I'd also recommend a manual rather than auto box as I found that the auto
2.5 I tried lacked so much power over the manual.
So that clinched it for me. I've never tried a 3.0 so I can't comment there
and I don't pay for my own fuel so all I can say is that the 2.5 isn't bad.
On a motorway run I'll get somewhere around 32mpg, dropping to about 20
round town ,but then I'm not light footed :-)

By the way the sport is not sportier than the rest of the models except in
looks, I initially liked the sport but the creature comforts inside swung
me towards the SE....now if the sport had been more powerful/faster etc....

P.S I'm in my mid thirties so I'm Jag's target market!

3.0 Sport in Jag racing green.

MPG is around

19mpg in stop start traffic
30+ taking it steady on open roads.
23mpg driving quite briskly (hard)
