I test drove every car in its class before I decided to buy the RDX. I wanted something smaller than the gas guzzling Cayenne Turbo I was driving. I wanted good visibility, good handling and reasonable fuel mileage and a vehicle I can put my golf clubs without folding down the back seats, which the Porsche, Audi, MB Ml all fail. The RDX has good acceleration and if you use the paddle shifter it beats just about any Suv at the stop light grand prix. The handling leaves the X3 for dead. Only negatives is the brakes. Several high speed stops in succession will cause the pads to vibrate. Dealer has replaced rotors and pads for free and admits it a problem. Also, nav screen is not bright
Seats are great. I'm in the car sometime 3 to 4 hours a day and no fatigue. Handling is better than most SUV's and the reliability is fantastic.
Brakes for sure, Also Nav screen is too light with sunglasses on. Backup camera is useless gadget on bright sunny days. Bluetooth should automatically go to speaker when you dial a number from the cell phone.
