well living in the sticks, on a big sporting estate with private, untreated roads leading to hilly irregularly treated roads and a foot of snow that has been lying for two weeks (and now packed down to 3" of ice) heres the observations from me and my neighbours cars:
My Sprinter – wholly useless
I hired a diesel focus with traction control as a substitute run about – I was pretty desparate too, required quad-bike assistance where the Golf and Leon below got out with the odd shove. I only planned to hire it for a day, it took me another 2 days to be able to get it back.
My sister in laws M reg Legacy – 4 wheel drive and narrow tyres – excellent, but could still require a push from stationary on soft snow.
My GF's 2005 Seat Leon basic spec – pretty decent, never got into more trouble than a quick push would solve
Neighbour No1's 07 Vectra – one night sleeping on a strangers floor just 8 miles from home and several enegetic sessions pushing and shovelling it up the castle drive, some of which had to be aborted
Neighbour No1's 08 Audi A4 – big wide tyres, waited till the snow was packed down before he even tried to move it
Neighbour No2's New Golf fairly basic spec – as good as the Seat, better than the focus
Neighbour No 3's Big new Audi estate with huge tyres…. she never brought it onto the estate for two weeks, it was in trouble within yards, so opted to dig a parking space for it beside the road walk the last 1/4 mile instead
The Groundsman's Ford Fiesta tall thing – pretty capable
His Lordship's car of choice over a rangerover and BMW 3 Series Coupe…. An 03 Passat Estate, he's a racing driver though, I don't think the RR would have been enough fun, or perhaps he was happier to risk smashing up the Passat
But the outright winner, was the young lass in the flat with a Mark 2 Micra that has been wholly oblivious to the snow and ice through out – deep snow, compacted slush, solid bumpy ice – its never need so much as a push from the outset
So – front wheel drive, light car with the skinniest tyres you can find is the answer.
Shame nobody makes them anymore.
