Sounds like you did some good research. Based on that info, I think you priced it pretty fairly and gave yourself a little wiggle room.Cause who ever buys it is probably going to want you to drop the price a bit... just so they think they are getting a deal.
The ol car salesman saying "Always make them think they are getting the deal"

Grandad doesnt want to go below $3700, but when we got it almost a year ago i think now, we actually paid $2700 (and the guy we got it from gotmit to sell at an industrial auction for 2600), then we swapped the battery and have had it insured the whole time so he wants to get that money back too, just doesnt seem to be much demand for them right now. I need to talk to him, i thinki could get him to take $3500, maybe $3400, need to call a guy who asked about it a few days ago to see if he's still interested, he just wanted a lower number since he's driving from south carolina to the middle of Ga.! But he said he contacted a number of people so he might'a found something a bit cheaper

Talked to him, he's a little stingy so i aint tellin him i dropped the asking price to 3600, but he said he'll take 3200 to get rid of it, and i get to use what i need to fix up our 85 c10 which has been suped up with a 350, bored out, flat heads, headers, new cam, holly 4-barrel, true dual with hush thrush or something (that's what dad said), and a new trans, plus he upped the rims to 16s and got some bigger tires, and a grill without the emblem, so it looks good
