Hi, I'm a taco driver now, first toyota was a 93 pickup before the tacomas were introduced. Gonna buy a new one now as I have "outgrown" my current truck. Thinkin' about a doublecab 4x4 offroad. Just haven't decided on a final color. If I pay $250 over invoice for an 07 have i negotiated well? I have a standing offer for that as it is. Any buying tips?
