So close to being perfect, a shame they blew a few details that make it less than so. The luxury/sporty balance is second to none. ML stereo sounds wonderful although XM sounds crappy (not Lexus's fault - it's XM's signal compression). The nav is awful. It suffers from obvious language/requirement translation issues in the design cycle - such a shame. Stupid limitations and just not user friendly. Nothing about it is intuitive. Speech recognition is worst- in-class - inability to recognize simple commands render it unusable. Bluetooth only auto-connects with one phone - how dumb is that. Very limited steering wheel controls mean constantly trying to navigate menus.
Leather, power, cornering ability. I like the fact that it doesn't sound like a throaty sports car inside - I don't need that. If the infiniti G35 rode smoother and wasn't so loud, I would have gone with it. For folks who want a real balance of power and luxury, this is it.
Improve nav and extend controls to the steering wheel. For example, if I'm surfing XM presets (only 6 at a time *sigh*) I should at least be able to see the current song - but no. It sucks. Car is unnecessarily heavy which hampers milage. It's only 300 lbs lighter than my old V8 LS - go figure.
