If you take the grand, make sure he knows it's non-refundable if he changes his mind. If your CL ad is as descriptive as this one, not much he could pick on. That's how I run my ads as well. This will tell you if he's really serious. Also price is firm. He wants to haggle, keep the grand and let him walk, he won't.
I looked real hard at your machine. It's half the price of a new grapple trailer. I'd love to have it, but can't justify it on the business side yet and I have a house rehab coming up that will tie up any free cash. Mama's looking forward to the house. Us and four kids in a mobile home is getting old.
If I were at a different station in life...
Looks real good for the price.
