The dollar thing with cars is a strange mind set. It seems like most of us Model A owners fret over ROI, can I make a profit? etc. etc. That's natural I guess.
But we will run down to the local car dealer and buy a new pickup and plop down $45,000- $50,000 and not think twice. Some go higher. In 8-10 years that thing is about worn out and has a value around 6 grand, maybe. It's OK in our mind to eat 45K on a new vehicle but not a Model A Ford.
Granted, the Model A will not do what that new pickup can and you're not really comparing apples to apples the point is the money 'lost'.
It has been my experience also the last few years, and I blame the 'reality' TV car shows, EVERYbody and their brother-in-law wants to get your collector car on the cheap, 'flip it' and pocket a big profit, puff out their chests, and proclaim 'I da man ain't I slick?' I get real and I mean real tired of guys approaching me wanting to buy my car so I just toss out absolutely stupid dollars to them, they often get mad

but I say 'You came to me I didn't approach you.'
Had this again just last week I just needed to vent

Some guy from Missouri driving around with a car hauler a local at the restaurant sent him down to my house. I'd just as soon have the Jehovah Witnesses drop by!!
