I recently bought a 57' 2dr. belair hardtop and according to some internet websites I came across recently, production numbers show my particular model topping out at 168,293 units. Have any of you here ever wondered how many of my model car or your your particular tri-five model car are actually still around that are registered and driving in the U.S.?? there obviously isn't 168,293. I wonder if there is even 100,000 left. Is there any way to determine this or has anybody tried doing the research?
