This is not the perfect car, but it is the perfect choice for the entry level small-luxo-SUV market. Felt the RAV4 and CX7 were not as refined. X3 is the only real competitor in this segment. The X3 was a nice car, but would cost about $10K more similarly equipped. I thought the ride was a bit fairer on the BMW, but I felt the handling and power on the RDX was superior. It has ridicoulous amounts of technology, plenty of power, and sport-sedan like handling.
Excellent voice recognition system navi, 2.4L vtec turbo, handling, build quality, good interior materials, comfortable front seats, rear-view camera, sun sensing climate control, Xenon headlights, XM-traffic reporting, SH-AWD, cool computer with tire-pressure monitor and other stats, plenty of nooks.
It is a very loud car. Need to add more sound/wind deadening material (probably at a cost of performance robbing weight), needs light sensing auto headlights, passenger power seats support. Memory seats, auto up/down for rear windows. Other then that - has almost every other doo-dad out you can want.
