It's only at $6,200 right now. It doesn't close until the 25th of the month, which would give you time to drive over there and give it a good look, that way you can decide if its something your real interested in.
Whoever that bidder is, has probably put a 10k or something priority bid in. Whenever someone bids, it will automatically bid for him until his maximum is reached.
If I'm looking at spending that kind of $, I like to go look, and talk to the owner if I can. Closer to home can save you $ on trucking, or enable you to pay a little more for it.
At least being Cat, you wouldn't have the parts availability issues like the Allis- you just have to be able to afford them.
Good luck finding something- I'll try to keep my eye out.
