I would say I'm a purist, although I'm not sure if I qualify since I haven't done any restoration work so I haven't had to chase down parts.
I think my car would fall into the category of survivor as it's never been modified other than required replacements such as fuel tank and probably an alternator at some point. It did get repainted to a color that was not original to this car but it was an original FGF paintcode.
I even have the original convertible top on it, but it's not in very good shape. No holes in it though. I only put the top down in the spring and back up in the fall when it's time to store it for the winter. The boot still looks great.
