Funny story - I was riding my bicycle one day and spotted the '50 Ford Club Coupe for sale in a driveway. Didn't quitee have my license yet. It was a V8 car with overdrive. Baby blue with a perfect interior, with dual glasspacks and wide whites. Pretty damned car! Seller wanted $500 for it, and in my youthful exurburance, I said "Sold!" I rode like hell home and dug into my "car fund", which had about $600 in it (I was 15), and that was a fortune in the mid-'70s. Rode like hell back to the car. Gave him the money, got the title, loaded my bike up and drove that puppy home!
I unloaded my bike and then did what any kid does with a "new" car - wash it! I had finished the job when a guy pulled into the driveway..."wanna sell that old Ford?" I forgot to remove the For Sale sign. I said "Sure, I'll take $1,800 for it!!" He hemmed and hawwed and shot me $1,200 as a counter. Nope! After a few minutes, I asked the guy "how much do you have on you right now?" He pulls out some hundreds and fifties and counts. "I've got $1,500 on me right now." I stalled for couple of seconds and said "well, OK, I'll take it!". So, his son was with him. The man got in the Ford, his boy followed him out, and I made a grand in minutes.
Just after the guy drove off, my Dad pulled in the driveway, and asked "Who was that?" Told him what I did, and he said "I had that car's very twin in 1954! Kinda wished you'd kept it for a few more minutes!" He congratulated me on my fine business acumen. I was pretty proud of myself!
