a 60s Camaro, didn't see the front so I don't know what year
Time for "Weekly spotting tip for Webby", with your host, SMS.
You don't need to see the front/rear of a first generation Camaro to ID the year. 67 has side door vent window, 68 does not. 69 does not, but of course also has the squared off wheel wells.
Now the quiz... what engine was in the 73 Corvette you spotted?
