With BMW, Audi, and Mercedes getting all the attention in the luxury crossover market, the RDX is too often overlooked. I have owned my 2011 RDX base (front wheel drive) for 8 months and love it. You get a lot for your $30,000. Stellar acceleration and handling, all the creature comforts, and a premium feel (though not quite as "premium" as the German competitors). If you want to save a few thousand dollars and still get an excellent vehicle- give the RDX a long, hard look before jumping into that BMW.
If you do not live in Alaska or extreme north east, consider front wheel drive for even a better value. I live in NJ and am getting through the winter just fine with my front wheel drive RDX.
The engine! Hard to notice that its a turbo 4 banger. Turbo lag almost non-existent. Puts out big torque (I think more than what Honda says). Could use direct injection though...
Handling is far superior than most other crossovers (except BMW). Has an almost sports car feel to it. Steering wheel provides positive feedback. The ride is not too jarring, as others have suggested. Its a perfect balance between sport and comfort. Base model is very well equipped- heated seats, ipod connectivity, backup camera (in the mirror). I love the exterior styling, but gave it 3 stars because its highly subjective- some say it looks like a minvan from the back.
The engine, while a gem, would benefit by the use of direct injection. This would significantly increase fuel economy, lower emissions, and keep things running cooler. When I try to think of a reason why Honda did not use DI, I scratch my head in utter confusion. Also, that transmission....It's a slushbox in the most basic sense. While using the "S" mode allows for your own gear changes- the shifts are slow and sloppy. At the very least, Honda could have put a 6 speed instead of a 5, or better yet- a stick shift! But, considering the price of the RDX, its not a huge surprise. Honda has always been cutting edge with its engines, not so much with its automatic transmissions.
