I'm trying to get a 1928 Whippet restored and could really use a lot of parts!!! I also have a 1927 coupe which is essentially just a frame, but with this horde could turn it into nearly a vehicle.
Are you willing to negotiate on the parts cache? I'm in Southern Alberta, which isn't that far of a jaunt to northern Montana. I'm just a guy in his 30s trying to make a go of these old cars!
But along the lines of what the other guys are saying, I paid $4,500 CDN for my Whippet and it was 75% restored (painted, wheels redone, engine done, trans done, brakes done etc.), and $400 CDN for a similar stash that came with the '27.
