Just as it seemed to have started melting, enough that I (somewhat prematurely) decided not to wear boots to go collect the car from the garage.
Well, good news is I collected it, it even came in rather cheaper than expected thanks to a helful and creative salesguy looking to sell service plans and the associated discounts (also fits in with my expectation I'll be hanging on to the car for another 2-3 years) and I even seem to have managed to go whole night with no further breakin attempts (mind you, it wasn't in a hotel car park - that will be the big test next week!).
Bad news is that, looking at the snow even now, I don't think I'm going anywhere any time soon. The roads round here have been gritted just once and that was on Monday when the snow was melting!
