//The Jimny is 3 door only and has tiny boot space -you wouldn't want to travel very far. Apparently a 2wd with winter tyres outplays a 4wd without-if you've got a 2wd cheaper to get winter tyres than another motor. //
That I seriously doubt!
Would love to see a reference to that!
Autoexpress did some interesting tests on winter tyres they're definately better driving on snow, very marginal in the wet and perform poorer in the dry
So all in all I'd say best avoided unless you spend a lot of time driving on the snow
As for your original question - beware 4x4s are often a lot heavier that means that they have a lot more momentum and can be harder to stop in the snow but they will get you moving in the snow when wheels are just slipping in 2WD cars
You really have to understand this - many people don't which is why you see 4x4s in the ditch so often when the snow starts
There are lots of different 4x4s these days so it would help to know what sort of size car you want.
Fiat Panda 4x4s have an amazing reputation for getting places you wouldn't believe if you're after a smaller car
The Dacia Duster is a bit bigger and very good value for money
