What's the best thing we ever found or the best deal we ever got? I am thinking a combination of the two, a treasure at a good price.
Two hit me in the head the second I read your subject title. The first was an NOS '64 Corvette shifter assy I got for $90! OMG I forget the details but it was something like '64-'65 Corvette only, I had a '64 at the time and I couldn't believe it when I saw the guy putting this tattered up GM box into this trunk as he was packing up to go home. I went and looked at it knowing exactly what it was and was willing to pay a lot more, the guy said "It's $100" and then said "But you can have it for $90 so I don't have to take it home" or something like that! What a treasure!
The second one was a pair of Buick Nailhead finned valve covers with the "BUICK" on the side.
I asked how much and he said $20. I handed him a twenty and had a number of people trying to buy them off me for a lot more as I walked around with them. LOL
Probably the absolute best deal was a 1948 Indian Chief horn I got for $30 and sold on eBay the next week for $280.
