This is my third LS (previously had 1990 and 1998 models). I'm on the fence with this one. On the one hand I love the vehicle's safety features, the interior, the gadgets and the acceleration. On the other hand the vehicle came with several problems - wind noise, hesitation at start, wing mirrors that did not unfold when they should, and locks that did not automatically lock when they should. All these issues have been resolved, but they left me concerned. There's too much road noise - the tires need to be upgraded to Michelin SP2 or equivalent. The engine sounds a little rough when accelerating.
Sound system is awesome, lots of gadgets, bluetooth works well with phone.
The navigation system is disabled when the vehicle is moving - there should be an override if the passenger seat is occupied. There should be more ways to get music onto the built-in hard disk, such as from an iPod or Audio-DVD. engine sounds rough and intrusive compared to my 1998 LS.
