A blue base model Camaro convertible was used as the pace car for the Lexington 200 United States Road Racing Championship (USRRC) race held at Mid-Ohio Sports Car Course in Lexington, Ohio on Sunday, August 20, 1967. Notice that the car has the base hub caps. I wonder if the car had a six cylinder?
The blue car behind the Camaro convertible pace car is the Chevy powered Penske Sunoco Lola T70 driven by Mark Donohue. He started on pole and eventually won the race.
