Just traded from years of driving BMWs and Mercedes for my first Lexus, the LS 460 with all the options except laser cruise. It is a nice car with great creature comfort features, but is it really worth the price tag compared to the build quality of german sedans (the jury is still out with me!!)? There is a lot of wind noise that should not be in a car of this price! It handles surprisingly well for a large sedan and gets great gas mileage for such a powerful engine!
Smart key, nav system, wonderful Mark Levinson surround sound system! Perfect paint job! Silky smooth V8 and 8 speed tranny! Reliability is supposed to be bullet proof compared to european models. Great dealer service!
Get rid of the wind noise!! Tweak brakes to not be so grabby. Improve fit and finish inside and outside (too many loose fitting items). Improve the voice command system. Try to separate the car a little more from its Toyota counterparts, meaning a luxury flagship should be just that!
