"Out of 117,604 1970.5 Camaros produced, only 12,566 had the Turbo-Thrift Six. How many can be left?"
Out of almost 125,000 1970.5 Camaros produced, only 8,733 were Z28's. How many could be left? I'd like to know this myself.
Agreed 100%, those were better muscle cars than the ones from its era, because they were smaller and lighter. If my googling is correct, a V8 Maverick coupe is even lighter than the original Pontiac GTO. Except they weren't called Muscle Cars, because the genre progressed into larger platforms by then. Which is unfortunate, but ...
If you look at how things got better over time but how muscle cars became bloated, the better aero, lower weight, more safety equipment (i.e. fancy steering column that collapses, standard seatbelts, etc.) shows that the Maverick just needed aftermarket bits on the motor to be a real performer.
