I'm with you on that...5 minutes looking at stock 911s or 930s, hours pouring over R Gruppe hot rods at any event...especially in the parking lots.
Biancaneve,
C 3.0 cars were not legal in the US as a production car in '76, '77. But quite a few were brought in under the 'once in a lifetime import rule' from the 80s. Rick Cabell in the New England area restored many under this provision. Here is one I restored a couple of years ago but have since sold.
