Looking at, evaluating and pricing a project car.

Make your money (and that includes value for a car you won't likely sell) on the buy, NOT the sell.

If "all it needs" is a battery- bring one.

If "all it needs" is a carb- bring ether- it should still at least fire and/or try to run (or bring a carb).

I changed the starter on my 440 truck in the PO's driveway so I could hear it run.
It had a cracked TQ but still ran enough to tell me the engine was good.

EDIT: BTW- $850 in 2015 for a 1980 step-side w/ LRE parts and clean bed with a 1969 440 and 833 OD. Now running and driving.
