FWD can understeer quite badly if you rely on engine braking in the snow (if you're used to RWD). Best keep a foot covering the clutch pedal when slowing for junctions etc... The whole "just floor it and the power will pull it round" crap is, well, crap. You'll smash into a kerb with full steering lock whilst spinning wheels wildly having influenced your direction of travel not a jot.
I don't think I ever got stuck in the snow with the Cougar, but the other car at the time was my old diesel Rover 620 and that was the car who's keys I'd usually reach for in the snow. Unless Gill had to go out too, in which case I took the Cougar.
It's not a Land Rover, but it's as good or bad as most other cars on the road. Snow driving is 60% driver, 20% car, and 20% tyres.
