Modern covers do not scratch and allow moisture vapour to travel through the cover. Sort of like Gortex. But ya, to each their own. I use mine in the winter or when there is going to be a heavy heavy rain storm.

Don't do it. A '74 and an '80's Carrera are two TOTALLY different animals. Any pre '76 is going to have the potential for corrosion damage, IMO. Especially since you used the descriptor Pristine.

Rent a storage unit for $100 a month. Don't leave an older Porsche outside. The under side will go to hell quickly.

As other posts have said even in dry garage enviroment older (non galvanized) cars will suffer from rust even from humidity - protect it - but use it and love it - My car is used reg. but lives in climate controlled de-humid garage... but I want it for the rest of my life & then my sons.
