Big Blue hit the nail on the head.
Although personally I wouldn't stand next to a Suzuki 4WD (ex-Landcruiser man as well). All I can really offer you is to keep this in mind:
"Why do you need the car?"
If you intend to take the car offroad then you will need a 4WD, not anything like an AWD - There is a very big difference.
AWD is safe as houses on the road, but will get you into trouble as soon as the going gets tough.
I have driven Suzuki's before and they are tough little rigs. LandCruisers are massive - but you need this (Big wheels,weight and clearance) for sand (why I had one).
RAV4's, X5's, (the whole SUV class) etc. are NOT 4WD's.
I remember there being a thread about the difference between AWD and 4WD some time ago, but I am technologically inept to be able to find it, and post the link here.
If you are going to get into a bit of mud, and climb a bit -look for a 4WD, the Suzuki will be fine for Switzerland...... it's made from egg shells and coke cans, but they perform OK.
They are light, have a short wheel base, and don't take to a high load very well - but I think that is all you need for here.
If you are just looking from a safety point of view (re: road traction) stick with your SUV options. The AWD has less transmission friction and are cheaper to opperate. All options here are a personal choice (personally, Subaru or the RAV, but it's up to you).
This being said - I don't think you need a 4WD in Switzerland at all
Hope this helps
