First off Welcome!
Now down to the topic and quesitons asked! I own BOTH vehicles! An 07 RDX Tech and an 07 MDX Sport/Entertainment.
MDX Fit and finish, quality are FAR superior to the RDX! RDX is sub Honda materials, where the MDX is WAY better quality. For example, the plastic interior parts in the RDX are hard like a rock whereas the MDX is SOFT to the touch, much like my 04 RL which is BETTER than both these vehicles! RDX has a stiff ride whereas the MDX is refined, esp. the "sport" model which is has the "Active Damper Suspension" exclusive to the Sport model so you have the BEST of both worlds (sport mode or comfy mode). Tech and base model has basic suspension....
RDX is loud, FAST and get LOUSY gas mileage. Infact I get better gas mileage with the MDX.
Its a no brainer, HANDS DOWN TO THE MDX! Ask someone who OWNS them before forking out all the bucks with folks here that are clueless.....Side by side comparisons can be viewed by "searching" on FABVSIX's previous postings!
No pun intended!
