I'd just like to point out that the Alpine in question is a 1955 Alpine.
This is not a finned model, but the Cary Grant/Grace Kelly style. I know
it weighed 2900 pounds. I do not know its CD, but assume it was worse than
the later Alpines. I'd be interested to know how your calculations work
for that car.
