As I have said Glenn you have to pick your days in winter and be sensible.Mine will be used this winter but a lot less than in the summer. It hasnt rusted yet in my 21 years of owning it and hopefully it will stay that way!
The 70s, 80s and 90s Fords certainly were prone to rust as they had virtually no anti-rust protection. When I lived in Australia I went to look at the brand new MK2 RS 2000 Escorts which were on show at a local Ford dealer in Adelaide and I remember being shocked when I looked underneath and there was already rust spots showing up!!
