hi i travel through flood water and snow but would never go off road. Will a 4x4 make much of a difference in those conditions? Some garages are saying yes but some are saying no! any advice would be great

Depending on the extent of the 'flood'. The higher clearance will certainly help (assuming you are talking about Land Rover type 4x4 as opposed to a Impreza 4x4?), but again that depends on how deep the puddle / flood is. The 4x4 element wouldn't really make much difference.

The big risk is floating away - that might sound silly, but lots of suv drivers get caught out in floods by assuming that they can drive through. If you see videos of defenders going through heavy floods they manage because they fill up with water.

In general I would advise not driving through floods unless it is a real emergency. There will be manhole covers lifted out of place and plenty of other risks.

For snow yes - 4x4 and winter tyres are great but remember that 4x4 helps get you going but does nothing to help you stop.
For flood waters the main advantage of a 4x4 is if you get a snorkel fitted. One of the main reasons people get stuck in water is because the exhaust gets flooded and the engine cuts out.
also you can't see what's under the water
so the answer is unless its extreme flooding to the point you need a boat a 4x4 will be better

But a snorkel goes to the air intake, not the exhaust, doesn't it?

I wouldn't consider this to be a real 4x4 - and wouldsn't dare take it near a field nevermind a flooded road

As one or two above have already stated - the depth needs to be considered and if it's deep then proper ventilation intake and exhaust must be considered.

You don't take a bmw to a stock car rally - you shouldn't take a yuppie suv (can't remember the "nickname") to a site that needs real handling/traction

The snorkel is for air intake to the engine. The exhaust gives a positive pressure and as long as the engine gets fuel and air it will keep running and exhausting. But don't drive in floods, suppose you may mean fords which are totally different.
