Proof that winter is approaching quickly was evident by the twinkling sheen of frost on my car when I left the house early a few days ago. This got me thinking of what we need to do to prepare our cars for winter. It’s not so long ago where cold damp conditions severely affected a cars reliability, however today’s cars are tested in all kinds of extreme conditions before they go on sale, and so we are relatively immune from the truculent behaviour of our cars on cold, damp days.
