My potential buyer called again this morning - wanted to make sure
that I "understood" his offer.

Get this - he felt that based on his "surveyor's" report that perhaps
he made an inappropriate offer. He went into this long explanation of
the why's and how's then said this:

"I don't want the engine as it's very old. Based on your asking
price, my "surveyor's" report and the cost of a new four stroke Honda
long leg which will cost me at least $3,000, I'll up my offer to
$1,000." Basically, he wants me to buy his new engine for him.

I told him never to call me again. :)

Ever.
