Hi, We have a 2008 GS460 and love it. As mentioned, the 1st shift from 1st to 2nd in the morning can be a shock, but after that the 8 speed transmission is a dream. The car can accelerate from 70 to 100 very quickly and smoothly. We love the seats, the sound system, and the ability to choose the suspension we want. We wish for a bigger trunk and a nav system that could understand us and not require us to be stopped to work. There are frequent comments about rattling sounds from the dash and, knock on wood, we haven't experienced that yet. We can get 28 to 30 mpg out on the freeway, plus, it's a great looking car. We test drove other cars, and as drive down the freeway we remember the BMW drivers can't figure out their music due to the idrive, and the Infiniti drivers can't hear their music due to the road noise. We love our GS.
