Researched them all and bought a used RX with 150,000. Confident because it's a Lexus. No problems at all. Had several Lexus models LS 430, LX 470 and ES 300, all been rock solid. This RX has same motor as ES, Camry, etc. With AWD gets from 17-24 mpg. Seats nearly as comfortable as my LS 430 due to higher seating position and easy in/out and strong seat heaters. Nice size, ground clearance, visibility, comfort, reliability. Sold on Lexus, can't go wrong.
Reliability, build quality, interior comfort. Enjoy the all-down window control. Center console is useful. Dash computer for MPG. Good blend of carlike ride with SUV features.
Gas mileage could always be better but good for AWD. Heated seats should be standard. Small tank and turn radius fixed on newer models. Navigation would be nice but for $200 buy a portable one.
