I've owned my 2013 RDX for about 6 months now.
You're going to get what you expect from an Acura ... good performance and reliability.
I'm getting about 18mpg, less then I expected ... but no highway driving.
Last month my wife spent more and got herself a 2013 Volvo XC60.
I'm jealous ... wish I'd spent a little more and got the Volvo also.
