Call me old fashioned, but I cant see how anyone in this country who isnt a farmer actually needs a 4x4.
I'm with you on that. The fact that so many people are prepared to lumber around in them these days I find difficult to understand.
Jag X Type 2.5 & 3.0's are 4x4, quite cheap too
Not 4x4 as in "any good in the snow" though, unfortunately. They are only 4x4 to cover up how dire a FWD car would be with that amount of grunt IMHO. My neighbour had one and managed to knacker the front suspension when he skidded into a curb on snow.

I assume you,ve never owned a 4x4 I,ve had 3 Pajeros and although the Omega is a fantastic motor It will not perform as good as a proper 4x4
Depends how you define "perform". For me? 0-60 significantly below 10 seconds, top speed comfortably over 120. Decent amount of agility on the twisty roads, low road noise, comfy ride, fuel consumption at an affordable level (high 20's on petrol, say), able to tow 1.5 tonnes without flinching...
Unless I absolutely needed to drive through a muddy field on a regular basis it's Omega all the way, otherwise I'd have to sacrifice most of the above.
