I think alot of you guys are just old, crotchedy weiners that are too worried about your comfort to accept the characteristics of a fox body as a DD.
I had a 69 mach 1 in HS. I had that car until I was 21. It got driven every day in all through the year in Colorado, and Iowa. Other than routine maintenance issues, it always started, and always went where it was intended to go. However, by the end of my "relationship" with it, it had become an obnoxious, big cammed, over carb'd, noisy PITA to drive that had Firestone drag slicks as it's only rear tires. All my fault for taking a fairly reliable car and turning it into what it became.
Everytime I see people advise against using one of the cars as a DD because of the potential for unreliability, I think "from what?" What is gonna be any different on this car from any other DD beater that you'd have to slash around in for the sake of keeping your "unreliable" fox safe at home so it won't break.
Obviously, depending on the condition of the car, an abused version will be a lot more suspect than one that's been taken care of, but I just cant subscribe to all of the "wouldn't drive one everyday" mentality. Ford made them to drive everyday when they were new, parts are sold to replace what breaks, most of the stuff is fairly reliable on the car (unless abused), and even if it does fail, most of the stuff is fairly easy to fix, w/ more than enough reference material to get it fixed.
What's not to trust?
