It seems with the right tyres , you can get from A to B is your is200 :) , i was looking on the Mytyres site at tyre prices, if your running 215/45/17 then the cheapest snow tyre is a Goodyear at £124.50 each :o , so thats a very expensive 1-2 months a year use.
I then looked up the IS200S, 16" wheel tyre size and a 205/55/16 can be bought for £56.00, so a cheap set of " S" wheels of Ebay ,and the cheap tyres,could be all sorted for £300 or less :)
Very nice, the "Stunner" £56.00 winter tyre....
