This car is a blast to drive. I'm a long time Acura MDX driver and the RDX is a lot more fun in daily highway/city driving. When I'm not cranking up the turbo, I seem to average about 23 mpg with the 2-wheel drive.
The stereo is hands down the best I've ever heard in a vehicle.
Rear seat air conditioning vents would be nice, but the car does cool down quickly.
