Just bought a 2007 LS460 ourselves. Have issues with it already. This is the 4th Lexus we have bought & with the other 3 problems were minor after having them for years ( including a 95 LS 400 bought used 6 yrs ago). After getting some minor issues fixed at dealership 2 1/2 weeks after we bought it I was driving it home today & engine has a ton of hesitation & is whining out. There is a topic on this on here. We are hoping it is an easy fix like a software update but if not we are thinking about returning the car.
