First,
Look a the picture in the sigfile and figure out what it is....
Now, that coach is wood framed box on a chassis that has sat in the mud for 10+ years. The chassis could well be corroded past recovery. If it has any leaks at all, the wood frame has rotted and may collapse. So look for evidence of water intrusion before you do anything else.
If it is dry inside, then get to the engine and use a wrench on the crankshaft to pull it through two (2 - Dos) full turns. If those two things work, it can probably be salvaged.
The brakes will need help. Just replace everything be the backing plates after you get the drums turned (if you can get them off intact).
The fuel system will pretty much have to be replaced. Everything from the fill neck to the carburetor will have to be inspected. Anything not fit for current "motorfuel" will have to be replaced.
Everything rubber and plastic is probably shot.
Now, once you get there, remember that the seller is seeing it in his memories and he is actually charging you to haul it away. Moving it at all is going to start at 200$us.
Other than that, it could be fun.
Be sure to look in on Tin Can Tourists.
Hint, the beauty in the sigfile picture is not my first antique.
