Agree with general review, power of the 250 is adequate, but not inspiring or thrilling. The fit and finish inside is nearly flawless except for the under floor "pumpkin" that significantly sticks into the drivers leg/feet area. This may be due to the AWD model I bought but it was still irritating on long drives when using cruise control and moving your feet around. The only other issue was the navigation system. The disk for the nav system (which became unreadable 2 days after I bought the car) is housed BEHIND the electric clock panel which takes special tools to remove (nearly impossible to do yourself). Otherwise very impressive amenities inside (courtesy lighting best I've seen).
Lexus original sound system is excellent, hands free phone easy to use and voice recognition suprisingly good. Ventilated/heated seats very effective. Interior lighting very well designed with small (I think LED) lights everywhere you need and want especially on long trips in front AND in back seats
PLEASE make the nav system disk more easy to update/change/fix! Better yet, replace CD player with a DVD player which are cheap and leave NAV disc in there. Power point location in arm rest difficult to access. Move "pumpkin" under floor adjacent to drivers feet closer to middle of car.
