I got $11K for my 2003 Sport Trac on a trade in for my Mercedes back in Jan 2008. That was about $1000 more than KBB or Edmunds priced it. I did have it completely detailed before I took it in to the dealer. It was on his lot less than a week and was sold.
I paid 17,700 for my 05 in mint condition with 29,000 miles on it back in October. If I would have paid $7600 I would have had a spare 10g's to put in some sick upgraded race motor. :grin:
