I bought this car two weeks ago, after looking extensively at the Acura MDX, which was the only serious competition in the price range. I have driven other RX's, and though nice, were too isolated in driving dynamics. The 2010 is far different. Its ride quality is similar to that of a Mercedes sedan. Solid, quiet, sporty, not isolated at all with a nice amount of engine noise. It has a nice heft and handles with aplomb. This is not an enthusiast ride, but when do you really need a sports car experience in an SUV? It is solid, extremely comfortable, and has excellent performance. The new NAV system is excellent, and the Ipod and Bluetooth interfaces work well. Satisfied thus far.
NAV remote system (it's worth the price); build quality; ride; seat comfort; heated and ventilated seats; bluetooth connectivity; keyless entry; rearview camera; Lexus reliability
USB and power adapter sockets are buried beneath two trays in the center console; center console buttons are a bit haphazard if controlling functions without the NAV unit; some cheap plastic bits (e.g. glove box cover and sunroof shade); no handy storage for small things like coins, etc.
