Exactly what makes a MOPAR a "Matching Numbers" car?

Chances are that it is a losing proposition either way unless you were way ahead of the curve and got in before people went nuts!
I believe that the only people that make money on a great build are the folks that you might farm work out to - machine shop, paint shop. Nobody should get into this stuff to make money. Build your car, build it like YOU want it, and enjoy the hell out of it. If you never sell it it won't matter how much somebody else thinks it is worth.

I see guys churn through car after car - fix them up and sell them off, buy another one and start all over again. One of my Darts I bought in 1975, another one in 1989, and they just get better and better over time, one improvement after another over the long haul.
