decent traction in the snow/ice with the SH-AWD.
cramped, not enough space for an SUV, but the lack of space gives the RDX a feel/handling of a car (doesn't drive like a boat, like some other SUV's).
zippy single turbo 4 cylinder engine. (won't break any quarter miles, but gets the job done none-the-less).
good looking accommodating interior, although it can get lost in the crowd on the exterior styling (lack of "exotic" styling).
mediocre gas mileage. (depending on your driving habits).
honda made parts = reliability.
can pick up a certified one up for pretty much dirt cheap.
*Source* Cousin has had one brand new since 2007. (7 years running strong). & had the opportunity of test driving a model year newer for work.
what makes you want an RDX as opposed to a different SUV?
