Hi All, first winter as a Caterham owner fast approaching. Any tips for keeping the car healthy, I have a garage and happy to take out on the dry days, avoiding freshly salted roads if possible. Wondered about petrol tank, is it best fully brimmed or near empty? Oily bits and brakes, anything else? Will have a trickle charger but may have to take battery out of car to connect it, as no power in that garage. Thanks!
