Well that was another bracing car wash today. I mean the ice on it did look quite cool (literally).
15 minutes running the car, let it warm up and a rinse and all the ice was gone. Then a wash and quick layer of Seal N Shine for good measure!
Annoyingly it's been intermittently giving me a restraint error that comes and goes. Not sure how susceptible these are to the seat sensors playing up like in my old E Class or something else. Something to keep an eye on and sort in the spring. May even just be that it doesn't like the cold haha
