Thanks for the responses guys and keep them coming. I haven't made my mind up either way but I do feel more attracted to the Suzuki due to its lower buy-in and simple mechanical nature. I thank all the GX470 owners for chipping in, but I had already considered that vehicle before posting, and it's just not happening. They are harder to find than 4Runners, plus I might be one of the few people out there who actually prefers a vehicle that isn't loaded to the nuts with bells and whistles. I don't really have an issue with the Lexus, it's just that, if a 4Runner's borderline too fancy and expensive, a GX470 is completely out of the picture.
They are practically the same price and you can find low mileage ones A LOT easier. It's not really any more complicated. Same basic truck.
