So I bought a new 2013 650i xDrive Gran Coupe loaded $108k MSRP...M Sport...20" wheels...and my wife and daughter HATE the ride in the back seat! When driving over what I call "normal" road bumps, I can hear my wife and daughter shouting out in the back seat every time their butts fly off the seat when I drive over a "normal" road bump. I can feel most every crack in the road right in my seat....and my wife and daughter say the back seat amplifies the bumps up through the suspension. I often hear the wheels hit underneath. A $108k automobile should NOT ride like this. I tried 19" OEM BMW wheels with 40R/19s.....they help..but it does not address the problem. I can hear the wheels hitting the undercarriage....load bangs.....it's really frustrating. I've tried Comfort+, Comfort, Sport and Sport+....similar results. Anyone else experiencing this? I understand it's a sport suspension...I own an M3....but never experienced such horrible ride quality. Unless you're driving on a mirror highway or track, the ride quality is horrible. I have an appointment at BMW on Sept. 3 to check the suspension. If they say nothing is wrong, i will invite the General Manager for ride in my $108k Gran Coupe and ask what he thinks of the investment in ride quality...then ask for my $ back. Any advice? Thanks.
