Did your dad work on the production line how good watching these sick muscle cars coming down the line.
My dad worked at the local Ford dealer at Hurstville. He and one other guy worked in pre-delivery where all the new cars were inspected, tested and accessory fitted prior to buyer taking deliver. The dealer sold about 4 to 10 new cars each week but on some weeks with fleet or police car deliveries, there could be 30+ in a week. In all his time there for almost 30 years, there were many V8s sold but only 2 shakers (HOs), about 30 GTs (2 & 4 door), 5 John Goss specials and 3 Cobras.
He was aware of the race tuned motor Fairlanes but none of the guys knew what the motor serial numbers were - that was a factory guarded secret. It was like a lucky dip for some buyers.
One interesting point my dad made was that the majority of V8 sales in the early 70's were to men in the 40-60 age bracket. Most younger blokes bought older Holden and Fords as they could not afford new V8s and credit was only known as a free game in the pinball parlour and not a piece of plastic or bank loan. If you look at V8 sales today, I would say that more than half would be in the 20-40 age group. How times have changed.
