IMO, price is WAY steep. I paid about half of that for my 56, with disc brakes and almost no rust at all. For $9k, I could have bought a running car.
There also seem to be some wrong parts : looks like a TR4 rocker cover & shift lever. Probably means it has a TR4 engine & gearbox; and I think I can almost see where the tunnel was pounded out to clear.
Wrong rear view mirror as well (not that it's any big deal).
And the blue plate would be from the 70's, which might mean it's not an all-California car (which also helps explain the rust).
I'm about 100 miles north of SD, farther than I'm willing to go for this car.
