Speaking of time machines - if your imagination still works, you always have one at your disposal.
A while back, we lost a very long term Chevrolet dealer in Nashville, the very one my car came from in February 1969 (28th).
My parents bought their first new car from there, a '57 Bel Air 4 dr. hardtop, which I grew up in. Other cars we bought from there - '65 Impala SS, '65 Corvair Corsa (i learned to drive in that one), '68 Impala Custom Coupe, '72 Impala, and finally my wife's '85 Z28.
Point being, a good friend of ours (who worked for the dealership) found some keepers before they closed - I tried to take as good a pic of them as I could - hopefully you can make out the 3 or 4 Camaros and the Chevelle sitting on the showroom floor. The Lemans Blue '69 Z in the back could be mine - and I wish I could go back to prove it.
Thanks, Sport !
