yes, they buillt nearly 2.000 Birds and more than the half of them is still out there. There is a registry and I think there are more like 70% of them still being around somehow.
the 1970 'Birds were Road Runner non-pillared hardtops right?
assuming thats right, the predictive "model" doesnt break Superbirds out from all the other non-pillared hardtops, but it "predicts" (round numbers) of the 25,000 non-pillared hardtops built, 3,700 should still be around, plus or minus 90 cars, today.
The Superbird Registry (they have been counting them since 1975) says 1200+ Birds are left of the 1900+ built, so 2,500 non-Bird RR's should be left. Model seems to recognize a "collectibiity" factor of '70 RR's versus a '70 Imperial coupe, basically estimating 15% should be left 45 years later versus 1.75% for the Imperial
How many of the 25,000 '70 RR's are really left? taking out the Birds, it could be 5,000 left but thats predicted to be less likely than the estimate of 2,500 left.
As rabid as the "Bird crowd is with their "flock", and despite being on it for almost 40 years, they still cant find a third of them. And some will never be found (recycled, sitting at bottom of the Atlantic Ocean, etc) , another one might turn up today...you just dont know.
Back to where we started, I hope we can find, save, or maintain as many of the 2,057 C-body LeBaron and Imperial Coupes from 1970 as we can..however many are left.
