Howdy,
I'm pretty new to 55s and here is where I'm at so far:
I bought a rig off
ebay, sight unseen, for about $3600. Owner said everything worked, "some" rust but no big deal, and he wouldn't hesitate to drive it across country blah bla blah.
Ok, live and learn (rig does run really well BTW, it's just the other "minor" stuff).
Another $600 for transport to my home.
Now I have a piggy that runs, but needs all kinds of other attention, and needs parts that are mythical in nature, or cost a mortgage payment (e.g. Weatherstrip kit at $2200 from SOR).
So.......bought a parts pig for $1200, plus $150 for the ferry ride and whatever gas may have been. Add in another $150 for craigslist "gotta have" little pig parts and manuals etc.
At this point I've got $5700 into the project, And I have two non-running rigs in my driveway, one of which is going to take at least another $5K to finish. Which, will happen, just slower than I thought


.
So......$8-$10k for a nice, finished rig seems like a pretty good deal to me right now. Maybe see if you can put down a down payment and get owner financing from a sympathetic 55 owner

.
Good luck in your search!
