Alternatives to Carpeting

Are you going to leave your car out in the weather? Drive it in the rain all the time? I know when I restored my 65 Barracuda back in the early 90's I never had it out in rain and it was always garaged. I sold it in 2007 after putting over 60,000 miles on it on nice days only and it looked as good the day it left my hands as it did the day I finished it. If you are going to do all this work to a car and not treat it like this well,you are kidding yourself . So,with all this being said,it really isn't about what floor covering you may or may not use, it's really about how you plan on treating your vintage car
