Went from Toyota Avalon to this, details are wonderful, fit & finish above Acura TL or BMW 3 & reliability. Plenty of power when needed, 350 can't keep up with the AWD on turns and traction for the average driver so unless you drive all straights or need to always gun off the line or are a true experienced sports driver - the 250 is great. Transmission is wonderful, smooth & smart either auto or manual mode. The ride is stiffer than other Lexus, don't know if its the AWD, wheels or suspension.
Keyless entry on doors, egine start and trunk. Gauges, interior lighting. Comfort of seats w/ heat and cooling, stereo - base has 13 speakers and is great. Power when needed and transmission is smart enough to always be in the right gear even when going up and down hills or in & out of turns.
Rear seat is very small. Would be nice if Nav was NOT packaged with the expensive stereo upgrade. Same for the Xenon lights with useless features which drives the price up. But I guess they can get away with it for being a Lexus. Or they just make everything standard like Acura TL.
