Storing a statesman

[EBII Fairmont]

Hi all,

My mate recently was given a 1972 Statesman, which used to be his grandpa's untill he recently passed away. It is going to be parked in the carport at their house, so how should he store it? If he puts a cover on it, will it hold moisture? That is the main question. He doesn't want to do something which will increase the rate its rusts, as the car is in top condition for its age.

All it really needs is a goody clean. But the major disappointment was when I opened the bonnet, and I only saw a six and not an eight :.

By the way, do any of you know roughly how much these cars are worth? He is still deciding on whether to keep it or sell it.

Thanks for your time.
Bill.
