Are you trying to imply that this is an $18K truck?
Hard to say without seeing interior/undercarriage pictures, but if those check out, personally i think the price is not out of line for a very clean, white, triple locked southern 1996 with very low mileage. Assuming all the maintenance is...
I have the door in that color i can sell cheap, but it's from a Lexus LX450, so it has extra holes in it for the Lexus cladding. I'll also be in Pittsburgh area in a couple of weeks and could take it with me.
Here you go. The part is actually called "air amplifier". AC amplifier (what the other guy posted) is a separate part, and not really known for having problems.
