First the RDX is NOT a luxury auto by any standards. The ride is so harsh that on a mildly bumpy road your head bounces off the restraint. On rough roads you had better hold the steering wheel very tight or you will get bounced off and lose control of the vehicle. I got over the lack of simple luxury items like seats that fold onto themselves and no power rear gate but the ride is something else. I am EXTREMELY sorry that I leased the '08 RDX. Acura has no clue that this is an issue as the response "well it is based on a truck" so I don't expect future models to address the ride.
Keep body style and interior and scrap the suspension entirely.
