LayinHP, I think you're right, I believe it's like 8% or something now.
We paid close to $25,000 for our nearly fully loaded 09 FX4 Luxury package supercab. The only option it was missing was the navigation system (it had the Sony premium Audio system). Off of the MSRP, I believe there was something like $12,000 off from Ford (list price is currently $40,000ish for our truck). Then our dealer gave us a generous trade in ($14,500 for an 06 Dakota Quad Cab SLT Plus w/ the High Output V8, Leather, moonroof, trailer tow package, and some more stuff, can't remember. I think it had 70,000 km on it, one dent in the rear bumper that was now rust, tires that were worn, and a crack in the windshield (though we paid for that). The KBB value for it was like $12,500 in excellent condition)) and a deal on the rustproofing/leather care/paint protection, and I think we got him to take another $1,000 off of that!
I think it all depends on what dealer you go to. Some of them want to get rid of their 09 stock ASAP, whereas others don't really seem to care.
2009 Flame Blue Ford F-150 Supercab FX4 Luxury package. And a bunch of other stuff.
