Hi guys, first post in a long while. I have acquired a 1970 mach 1, I knew it was an original old car but I am finding myself surprised by how original. The man I got it from said 21,000 miles to look at the car I thought 121,ooo but still original. 95% original paint, original seats and carpet, it reminded me of how you saw these cars in the late seventies, you know not perfect pristine cars but largely original and complete, if tired. Well when I started looking it has all the stickers and tags still in place, the original plug wires and hoses, even the bypass hose and the clamps are painted blue, voltage regulator battery cables all untouched, chalk marks on the radiator support and rear end etc. Now my problem is this, when do you not touch a car like this? It is not drivable as is, all I wanted to do was clean it up, change the fluids, tune it up and drive it as the survivor it is. But now I wonder if I start replacing even wear items am I doing a disservice to the car and the hobby? But I don't want a museum piece that I can't drive. What are your ideas on this topic. I know Bloomington recommends that some corvettes be left untouched as reference cars, is there a similar idea about mustangs?
