Hmm...............
Values?
Techniques as far as wrenching, rehab, cleaning, troubleshooting?
Wheeling, dealing, negotiating part?
For values we have the Vintage Value sub-forum.
For techniques, we have this forum.
For the ugly money side,....maybe Flipping 101 would be good.
I'd just hope the cross-pollenation helps me find what I'm looking for, not make it harder.
