I bought the RX after an extensive search and over three dozen test drives. The RX is best overall in reliability, safety (backup camera has already saved me a couple of minor bumps) and comfort for any family vehicle that I looked at. Any other car and I'd be giving up on one of the three. I got the Mark Levinson (as a result, the DVD as well, c'mon Lexus!) and it is awesome. The leather is very, very nice. Back seats are comfortable and recline. Rear gate can be opened and shut by remote, which is great during the school drop-off. Mileage has been around 16 around town which is not the best, but on our last 100 mile road trip, we got 28 mpg average on the highway. That's awesome! Congrats to Lexus.
Highway MPG, safety rating, Mark Levinson stereo a real treat, smooth ride, bluetooth, NAV (in french even!) auto rear lift. Backup camera is great.
Better MPG around town, make dvd option by ITSELF, two sunshades (only one for the driver?), strange downshifting on slowing down.
