The most "significant" Chevrolet performance car.

[Les Quam]

You guys are talking about generic non specific rare cars with the exception of the Z-28 CV mentioned by Colin.

The reason the unrestored blue ZL-1 is arguably the holy grail of muscle cars is because it is a rare car like many that have been discussed in this excellent thread BUT its condition and options for what should have been a race car like most ZL-1s were is what it sets it apart from the rest.

An original unrestored unmolested highly optioned RS ZL-1 with a documented history makes it number one Chevy IMHO. If the Z-28 CV mentioned by Colin is unrestored then it has to be up there except that the ZL-1 is a much stronger running car than the Z-28. Big block Chevy is really the pinnacle of 60s performance I think?

Now a really interesting discussion is this? I think Charley's not so super snake is the number one most significant Ford muscle car ever built since we are excluding Vettes and Cobra's as sportscars and not muscle cars. Here is the query, between the blue unrestored Zl-1 and Charley's not so super snake which is more historically significant? We need a Mopar muscle car candidate a specific car perhaps a Pontiac and an Olds and lets get ready to rumble and choose the holy grail of muscle cars?
