I got about 7K for the trade in. Pretty much KBB and I was fine with that. paid a bit more for all the add-ons, but basically wound up with a 7 year 125,000 bumper to bumper warranty and a 6 year maintenance plan. So, it is a fixed cost for the car (aside from gas and tires) for 6 years. Which is just what the wife needed.
I am definitely having issues with what to buy next though. It will either be a newer (no IMS) Boxster S or Caymen or a pre-99 911 (unless something pretty spectacular crops up for more recent models) as I like the body shape better. But I have not driven a pre-99 911 either and may decide it is just not the type of car I want (handling and creature comforts). Have to give it some time.
Of course, I could always win the Porsche lottery and then would be set.
