We have a 2007 GX470 with 110K. The truck has been extremely reliable with the only large non-maintenance item being that the dash split which Lexus swapped out under "good will." While we are 60k miles behind you our plan is keep it forever. We like the extra space provided by being able to take out the 3rd row of seats which provides more space than the new version that folds down. Of note, we intentionally bought a non-nav version so that we can swap out electronics as new tech emerges. We have updated our aftermarket system twice and each time we do joke that it is really makes the car feel new. We figure we can do a lot of maintenance and still come out ahead of a $800 car payment.
