Been at work today in the Libra 10 miles from home has just taken me 4 hours on main roads .Problem was dual carrageway was sheet ice and is up a hill.Libra got up so far but it then came to a stop.Come to a holt then just sat a spun up the passangers side rear wheel.Had to wait for gritter and a push.Think I need a LSD or a 4 wheel drive. When I got off the main roads I become a snow plough.

tyres ?

proper winter ones make hell of a difference

I once turned into a pub car park in my Europa and it bellied onto the snow and got stuck. Took 2 days to get it clear.

Snow chains can make a hell of a difference too - my MX5 on snow chains will push itself through snow a foot deep...

or get yourself one of these...
