I personally enjoy the time-machine aspect... I want to be able to jump in a time machine, and experience what it felt like to drive a brand-new, tight, rattle-free, and factory-assembled Mustang (or any other classic) off the dealership's lot, and what that would have felt like. I want to experience what it was like to cruise around town in that brand-new car.. I want to lose myself in another era.
So I'm pretty much a fan of stock. And when stock isn't working right, I know darned well (from my experiences in driving ultra-low-mile examples) that it ORIGINALLY worked darned-right, and the challenge is to get it dialed back in properly or tightened back up, not to reinvent the wheel.
But that's just me, and I can TOTALLY understand and appreciate the desire to modify, improve, personalize, and generally dink/dork/fiddle around with you classic!! The point is to have fun!!
So I don't begrudge anyone their right to do things their way, the way that they find to be fun and fulfilling and best. What annoys me, is when folks begrudge us "stockers" as being somehow boring, or sticks in the mud, or "snooty purists", etc.etc...
We're not that at all... You just don't "get" what winds our watch. It's a going back in time, looking at the car as a window back into history, kind of thing. Nothing boring about the thrill that gives me.
It's all good, in my book!
And P.S. - The notion that if you're 100% stock, and fully-restored, that somehow "now you can't drive it"... That it now is relegated to the garage, trailer, or a museum. Well, that's pure nonsense too.. You can drive an restored-original car daily if you've got the constitution for it. But people do what makes them happy, and if it makes them happy, so much the better. At least the cars aren't being crushed.
