Gears? I'm guessing you went 3.92.
The trades do cause a bit of a "shift" in numbers valuations. Everything that I've read (never tried it) was to get the out the door price then introduce the trade. I haven't traded so... don't know about that.
It sounds like they did do you right so to speak, dare I use the term "a good deal"
since they were willing to take off the dealer hold back and any qualifying rebates.
Was the dealer one of the DC ones that throws the transportation ($1600 ish) cost in at the bottom of the deal? I found that strange when I attempted to get one from a forum sponsor in the DC area.
