Mark, I am no expert, however this is what I do. Bearing in mind I keep the car in a nice dry garage. In the four years of ownership not one month has passed without being able to take the car out for a drive. Over winter if the car has not been started getting close to the month, I run the engine until the cooling fan goes on and then off.
I love going out in the winter when it is nice and crisp.
I do not intentionally take the car out when the roads have been salted. I tend to wait until after rain has washed the salt away.
Against the usual recommendations I leave the hood down in the garage, rather than putting it up for storage and then down for use, as I am worried about cracking the clear rear panel. I do keep the body work clean and a wipe over with detailing spray. If I were not able to drive the car during the winter, I would have to do some of the actions such as putting on inflating tyres and putting on axel stands for the duration. I hope that helps.
