I own a 2010 LX570 and the car is more than I expected in every way. I would buy it again in a heart beat! I don't recommend you get the 2008 or 2009. In 2010 Lexus changed from "Lexus Link" to "Destination Assist". It's much better, offers better services and the big advantage is that you can call them while you drive and they can download your destination(s) while you drive as well. (Very useful). The 08 and 09 had a hard drive option to store music downloaded from an Ipod. The 2010 no longer has the hard drive option, (i wish it did) but you can play the ipod directly thru the nav/radio system by plugging it in. You can do the same with tho 08/09 but the ipod does not charge while in use. In the 2010, there are two connections to the ipod availavle, a usb to play music and a regular jack for charging the ipod. So in the 2010 you can play the ipod and charge it at the same time. (I could care less since I mainly listen to news and talk radio anyway) In the 2008 and maybe in the 2009 as well, the car came standard with 18" wheels and optional 20". In 2010 it's only available with the 20" wheels. (20" wheels look nicer) In 2010 they had only 2 options as far as I saw. Fully loaded with rear seat video or fully loaded without the rear seat video. (Mine is without since my kids are in high school). In 2011, the prices of the car went up significantly. So Lexus now has 3 versions of the LX570. I don't remember the exact options on each, (Check them out at the dealer) but I do know that the fully loaded one had 3 unique featers that were not available on the other two versions. Heated steering wheel (Great option that was not available on the 2010 LX), Rear seat entertainment and ice box in lieu of the center storage box. I have not personally seen an LX with the Ice Box, but from what I can tell it totally replaces the center storage box. If so, I would be hesitant to buy it since there really isn't much storage without that center box and I have a lot of STUFF in my center storage box. There is another option (radar cruise control with pre-collision) but from my investigation it is only on the brochure. Good luck trying to find a car with that option. In 2010 Lexus did not bring a single LX into the US with that option. I think it's an excellent option (I have it on my LS430) and would buy it if it was available. Maybe in the 2011 model year they are actually shipping LX's with it to the US. The used LX prices are very high. From what I can tell it almost doesn't pay to buy a used one since you don't save much. If you plan on keeping your car for a long time like I do, it pays to buy brand new.
