How to live to old age in the Mopar hobby

I bought, fixed and sold a great many other cars and trucks over the years to finance my "addiction", most of the time I made a reasonable profit on any vehicle that I bought to resell, a few I made a really good return, and a few I took a shitkicking on.
I try not to worry too much about being upside down on a car that I plan to keep for myself for a long time, I figure the fun I get out of it is worth it.
These days I don't have the energy or the time to flip cars like I used to, my wife is ok with that, she doesn't like the yard to be cluttered with junk, so I keep it to a minimum, she stays happy, and doesn't mind when I spend a few bucks on my projects. It definitely helps that I do almost all of my own mechanical work, including looking after our daily drivers as needed, saving considerable amounts over having to have someone else do the repairs and maintenance, and freeing up cash for my projects.
I agree that finding someone else's project that they have bailed on can be a bonus, provided that the work is of reasonable quality and doesn't need to be re-done. I try to find good used motors and trannys when I can, and look for a good useable interior on most projects, or find a parts car with a clean interior, and as many good parts as possible, which has gotten much more difficult since some people are now restoring cars that would have been considered too far gone 5 to 10 years ago.
