EL5DEMON340 you can't buy a solid 70,71,72 A-body up here for twice that,those deals disappeared about 15 years ago.A decent swinger builder non numbers project will be 6 to 8.
And we come back to exactly in which part of North America you may be standing in when you start talking car prices. Not everyone has easy access to clean, cheap sheetmetal. The rust belt of upstate NY (where no salt crystal shall go left unspread on the roads) put a hurt on certain cars here ages ago. Sorry, just because a person can pick up clean sheetmetal for a price in one area, please don't assume it's that way for every one of us.
I think it was Small Block who pointed out the idea of putting cash under the seller's nose. Some guys will price high and wait for a counter offer. If you want the car, start the negotations and see where it goes.
