is my car in any way special/rare or more valuable than any other? 70 340.

I'm not a fan of pro touring either, but its a lot less garrish than pro street. That car looks like it was put together a long time ago judging by the patina(did I spell that right, I don't want to be called unintelligent). I love the flat black engine bay. It screams " I was built by a Camaro guy!"
Once you start getting stuff like that fixed, it will be a lot better.
My car's way more of an abomination than people who look at it know. Its all in the presentation.
