Test drove BMW X3, Lexus RX300 and Audi Q5 2.0. I can say the RDX was a winner hands down. Powerfull engine, luxurious interior, quiet, smooth and comfortable ride, excellent navigation. All that for at least 10k less than other 3 brands. I liked the Acura's straight forward pricing. FWD or AWD with technology package or without it. BMW, Lexus and Audi starts at the similar base, but by the time you ad few essential option packages, the price skyrockets to 50k. Audi tries to make you believe that their's is the only luxury SUV, so you should not even think to pay below the sticker price. what a joke. The Acura RDX comes fully loaded, no confusing packages and pricing. Very pleased.
Excellent V6 engine with good MPG, nicely, luxuriously appointed interior, quiet, comfortable ride, excellent audio/navigation system and last but not least very relialable. Honda/Acura, job well done. Acura RDX is a definition of what a luxury mid size SUV should be. Competition has a lot of catching up.
Maybe a panorama sun roof, other than that can't think of any.
