I've got the 09 LS. I'm not one that really fussy about the ride of a car and overall it rides nice. Nice feel, well composed over hard bumps and a quiet ride but quiet only on smooth roads. I feel and hear every little bump. It seems as though the body is constantly in motion. Every little bump upsets it or jars it. I've read through these forums and not heard anyone describe the ride as I have but instead use words like smooth or plush when describing the ride. Tire pressures are reading 29 on the DIC and verified with a digital pressure gauge. My last car was the 2004 malibu (I hated that car with a passion from 1000 miles on) and the overall ride of the 04 is no comparison to the 09 but the ride was noticeably softer and less busy/jittery. Did I get a defective one. Probably another lemon like my last car.
