1972 duster 340 value / worth ?

Looks nice enough from the picture. Three basic kinds of guys buy old cars.
#1. This guy likes to fix up cars for a hobby or profit. Doesn’t mind doing a lot of work and maybe taking years to do it.

#2. This guy likes to drive them and piddle with them. Buys a nice finished or almost finished car. Doesn’t want to do a lot of work, just have some fun with it.

#3. This guy has low skills and / or a limited budget. Buys a rust bucket with big dreams of fixing it up. Most of these don’t end well.

#1 and #2 have the best chance of a happy ending. #3 not so much.
