Keep it stock, or make it your own?

Obviously, its your car do what you want.
Having said that, I think it all comes down to the car.

Panther Pink 1970 340 Dart Swinger 4 speed car...Back to original.
1965 Plymouth Valiant slant six auto. Do what ever the heck you want. Depends on the situation to me. And before I start any car, I come up with a plan for it, and then execute it.
