I did two car related trades - one was 4 pins and a golden tee for a gorgeous 1977 gran prix - I remember high speed, Friday the 13th, and I can't remember the other 2 - one was a system 1.
I think it was fair for both of us
the next one was my 1957 chevy (seen on the pickers episode in which they bought an ek pinball in Johnston ri)
I traded that for my old 67 mustang back, a mint seeburg c jukebox, and a lot of rare woodrail pins. all total about 12 pins. I told the person he was giving me too much, but he wanted the car and it is what he offered.
I sold everything but the jukebox and put almost 40k in my pocket - I was willing to sell the car for 18k - but this offer was a no brainer
I can still see the car today - sadly it sits outside where it was seen on pickers
