Tractor or Fiance'?

In my quest to learn as much as I can about tractors, especially the cost for a good used one, I've been searching craigslist for used equipment. The other day, I came across the following ad. This was just too funny not to share.

***TRADE DIAMOND 4 TRACTOR*** - $13500 (Nashville,TN)
Date: 2010-02-25, 9:41AM CST

I have a diamond ring that was verbally appraised at $13,500.00. It is a 1.51 carat princess cut center stone, VS-1 Quality, K-color, with a .40 carat Trillion on each side, total of .80. Total carat weight is 2.31. It is set in white gold. I have the paper work. I am looking for a GOOD running tractor with bush hog for trade. I prefer a diesel 4x4, but will consider any tractor in good condition. Bought a place in Centerville, and need a tractor with a bush hog to keep pastures mowed. Willing to take a loss on the ring, and trade for a tractor valued around $7,500.00. Should have bought a tractor to begin with, cause the fiance' is gone, and I would have still had the tractor! Luckily, I got the ring back! The ring really is STUNNING! It got TONS of comments! Ring is in a Safe Deposit box at the bank. Will post pics when I get back in town Tuesday, 2/23/10. SERIOUS INQUIRES ONLY! Please DO NOT send me ANY get rich quick idea's or scams. YOU WILL BE BLOCKED!!!
