Thanks AndyW.. pretty much all stuff i'm ready to deal with. For a full-size SUV, i'm going to have to deal with bad fuel economy no matter what. The immediate competition is the Ford Expedition, and Chevy Tahoe and/or Suburban. I think they might get 1mpg better on average. I did a bunch of reading today on the brake/rotor issues. The4Runner actually has a similar problem and can be solved by installing slightly larger rotors and stronger calipers and pads. I suspect this can be done with the Sequoia as well.
I also read that a good number of these have this weird issue where the VSC, ABS, and something else lights all come on at the same time. It appears to be a fairly easy fix aswell.
7K is lower than I was thinking, but hey, what's th worse that can happen.. they say no and I offer a bit more.
