I just saw a 1971 3.0csl sell at Mecum for $185.00. It had triple Webers so it wasn't stock, very encouraging.
That's without commission. 203K total.
The fact that it made it to $185k is still amazing IMO... very surprised the reserve wasn't met at that level considering the engine, ect.
There are so few data points on the early ones it's hard to know where they're at.
