Back in the day, Sports Car Graphic Magazine had an extended classified for sale section in the back pages. Some enterprising soul bought several of the now-redundant Ford race cars, did some amount of refurbishing and, after installing air conditioning, had them for sale as daily drivers for the un-heard-of expensive price of $10,000 each. There was talk at the time that some inventive college senior tried to do a deal by offering a significant percentage of his not-yet-settled next year's salary. The offer was turned down although, as I remember, what he was offering was reliably estimated as being more than the $10 K.
As another comment on dollars from the long-ago era, I knew the guy who bought, for some small sum, Dave Lyall's A/F/X Falcon. Some months later he came to me after his engine deal fell through, and suggested that we go partners by using the 427 engine and Top Loader I had in my garage. I turned him down due to a lack of the money necessary to campaign the car after it was put together. A couple of months later, having got no-where with his project, he offered me the car for free if I'd only come and get it from his back yard. I didn't even have a place to put it and turned it down.
Several years later, with a non-descript FE in it (maybe a 390) it sold for several hundred thousand dollars. I wonder where it is now and how much it's now worth.
