I've owned about a dozen.
I don't really "restore" them, just fix what needs fixin' and maybe add some factory or period correct equipment here and there.
I've been pretty fortunate, and usually break even when they get to the point that the next item than needs fixed is going to be a costly one, and I deem it time to sell.
If you factor the value use of the car over the time owned, versus the depreciation for a newer car over the same time period...I think I come out ahead.
The secret? #1- buy low, sell high. I know sounds simple, and easier to say than do.
#2, buy cars with good quarters. Again easy to say, not to do.
#3, buy "desireable" cars, and know the market. Once more, much easier to say than do.
When coupled together, VERY difficult, but then if it was easy, everyone would be doing it.
No disrespect, but starting with a 3500 six cyl car is probably not the way to do it.
I passed on lots of cars before I bought my last.
I looked at several desireable cars with bad quarters.
I looked at several six cyl cars.
I looked at cars that were listed at a price closer to retail.
I ended up with a car with almost perfect quarters, that can be fitted with numerous "desireable" "factory" options, and was bought below wholesale price.
It's not the most "desireable" car, but it's close (1973 318 Satellite with working factory a/c), and with the good quarters and a few "value adds" (rallye mirrors, bucket seats, and tuff wheel [total cost- $250) already installed, and a few repairs )master cyl, trans lines, odds and ends) it should hold it's value and maybe even appreciate.
