I bought our 2004 GX470 in 2012. We owned it for 2 years and 7 months. It was a good vehicle for us and the engine/transmission are rock solid. Personally, looking back, I would buy one with LESS features. The dynamic suspension is expensive to replace, for example. I also had to replace the sensors for the rear air leveling as they both failed on separate occasions which was VERY problematic on a 500 mile road-trip. Also, others that note there's a "transmission CLUNK" should realize that it's a slip yoke on the driveshaft that requires greasing. A 30 second fix.
I absolutely LOVE, LOVE, LOVE my truck. I bought it used. I was skeptical at first because it had a lot of miles on it, but this truck rides like a 2011, its smooth, comforable and reliable. The interior is beautiful and I always get compliments on it. People actually think my truck is a 2009. I have not had ANY problems out of it. I was actually thinking about getting the BMW X5, but boy im glad I didnt. I could go on and on about my Lexy, but if you have one you know the feeling.
I purchased this new in May 2004. I have never been more happy with a vehicle purchase. Everyone loves this vehicle from the exterior look to the interior feel this is as close to perfect as they come. This has great power for the highway and is amazing in any weather or terrain. I have taken this where no other could go. Deep snow is no match. Off road is so easy. I use this to haul and deliver equipment to my clients and I could not be more happy with this vehicle. The Mark Levison sound is great! The navigation gets me where I want to go. Everyone feels safe when I drive them in this vehicle. Fill it with gas, do standard maintenance and it goes and goes.
Love my 2004 GX470. I have never had any major issues, just normal maintenance. I would highly recommend this SUV - not too big, not too small, not great gas mileage, but not bad, just an all around great car. Very comfortable and a great ride. Despite all the issues with Toyota, I would buy this car again...especially if they change the rear door!
