Thanks Justin I'll respond for no other reason than in case anyone is interested. I appreciate a thread about not buying a car isn't what people come here for.
Anyway, I'm sure you all appreciate prices are all over the place right now and as it stands I'm scuppered wth high Subaru prices and no main dealer within 30 miles.
Hanging onto the mitsubishi for now, it just works! Like I said in my first post it's hard to replace but I'm drawn to an outback.
With the tyre question I landed at this position. My Xtrail, Captiva and Outlander have all been awesome on OEM tyres in the snow (maybe two weeks per year max). I guess an all season tyre will be a little better and I don't care about the rest of year compromise unless its a significant amount of noise.
