Many thanks for the replies, always much appreciated. Good point about the snow - if it is that bad will use a work car! Sounds like keeping the 17" and either going for a tyre swap and storage or a spare set of alloys. Begs the next question, 18" and good summer tyres???? But I'll spend some time reading older posts and wait till I've seen 18" wheels on the car. I'm a bit too old for max power, just want a nice balance of handling & grip. Having just spent the weekend away from the car, can't wait to drive it again - best thing I've owned since TVR days (argh the temptation of the Nurburgring....)
