I owned a Toyota 4-Runner for 3 full years. It was a wonderful vehicle but I really wanted something more refined. The GX 460 fits the bill perfectly. I am not a fan of the over rounded rear vehicle cross-over SUV?s. They all look the same, the shape of the cargo hold isn?t practical and they rarely even handle a few inches of snow well due to run-flats and low profile tires. I applaud Lexus/Toyota for refusing to go along with the cross-over crowd on the GX and 4-Runner models. When I compare the GX to the 4-Runner, I would say it?s much more refined on all fronts. The V8 engine is smooth and quiet, the acceleration is very solid - not a turbo, but more than sufficient, the seats are extremely supportive and comfortable, the Mark Levinson sound system is fantastic, the build quality and reliability are exceptional. Purchase this SUV with confidence. I?ve owned almost every make and model of SUV on the market and the GX is hands down my favorite.
