Paid $6500 for my '56 3100 in 2000. Came with $3000 in receipts for body work completed mainly on the doors. Drove it for two years with original drive train and primer spots. Currently have $31,000 in it.
When I started working on it a guy told me to open up the parts books, locate my mechanic and body guy, and compute the total cost and time spent down to a gnat's patootey--then multiply by three. He was right!
