For the price I assume you also get the tape measure? Based on how it looks I would say a 4K wagon...
I sold a 1967 Dodge Polara 9-passenger 383 wagon in 2002 for $7,800 that was pretty sharp! The guys' asking price isn't out of line, IMO. The 318 Poly with the 3-speed manual trans was the base engine and trans for this car in '66. You could get a 225, also. Find another, gentlemen. He can't go up in price, but I'll bet he can be dealt down with cash. He's a flipper, so you can figure he has $3K in it. Maybe $4K. BTW, NOT my car.
