For an SUV it's very good with plenty of space unless you have a family or carrying more than 5 people, then some issues arise. The third row isn't exactly spacious and kids will fight for the mid row to avoid the third. Gas mileage is self explinatory since it runs on a V8. Power is plenty when you need it on highways and even after years, the GX is still fairly quiet even with a V8. All in all, it is a great SUV, just be prepared for gas trips and the questionable third row.
I traded up from a FJ Cruiser to this. In short, it's an amazingly comfortable SUV that excels at off road performance. Based on the Land Cruiser Prado sold pretty much everywhere else in the world except the US (think sand dunes and the bush), this truck is NOT a pimped out 4Runner. The full time 4WD, V8, rear air suspension, build quality, comfort and reliability combined make this rig unsurpassed for those who venture beyond the mall. These trucks are often referred to as out of date dinosaurs, and are compared to their unibody competitors who may outperform in terms of drivability and road manners; but this truck is built for towing, adverse driving conditions, and off-road capabilities while maintaining superior daily driver comfort for the whole family. If that?s not what you need, then look elsewhere. If it is, then look no further, spend a little extra up front, and drive it for another 200k miles. The KDSS version will decrease road body roll and improve off-road capabilities, as well, but they are hard to find. Not so great features include: limited 3rd row seating space and comfort, high (but rare) repair costs, fuel efficiency, styling (face it, it's ugly front most angles), and rear door.
Of all the vehicles I have owned, this must be the best one suited for the whole family. Used to drive an Infiniti Q45 that was an excellent vehicle but not enough room, my wife drives a Honda Pilot, which I dread to drive because of intolerable road noise. The GX470 is the end result of my hours of research and test drives. It is like driving in the quiet comfort and luxury of my previous Q45, with the roominess of the Honda Pilot.
Traded my 2001 4Runner for a 2008 Lexus GX. What a great upgrade from the Toyota model to their luxury brand. This vehicle rides amazingly smooth. It is a little thirsty on the tank, but hope this improves over time. The seats are extremely comfortable and all the features in it are just wonderful to use. We love the looks we get riding around town in this. You see why Lexus is at the top of their game.
After driving a Durango for many years, we wanted something a little nicer but still powerful enough to keep up our active outdoor lifestyle. We were looking at the Sequioa, but decided that for a little more the GX had all that we wanted and more. This is a great deal. The vehicle performed on a recent road trip under conditions ranging from 110 degrees to below 32 without any issues. It handled on ice, snow, mud, dirt, rock and pavement better than expected. Performance is unbelieveable when you accelerate. It tows like a truck and the engine doesn't even balk. Sometimes it is easy to forget that you aren't driving a luxury sedan. The only close competition is the Mercedes GL class.
