Any V-8 powered vehicle will definitely be discounted...
I took the opportunity this summer to sell our 2003 Focus Wagon with 50K miles on the odo, for $8k. I then purchased a 2004 Toyota Sequioa Limited (leather, power everything, sunroof, tow package, heated seats, seating for 8) with 60k miles for $12,800. Believe me, stepping up to a loaded Toyota Sequioa from a fairly pedestrian Ford Focus Wagon for only an additional $4,800 is saying something! The Focus new in '03 was a $20k car; the Toyota new in '04 was a $37,000 car...I'm still stoked about the whole deal.
