forgive me if this isn't considered technical, but it seemed the best fit. I love, love. love my car, but going over speed bumps or on uneven pavement is hard on my body. I am not expecting to glide over rough patches, but it would be nice for it to be a bit smoother. any suggestions on what I should put on? I am not a diy- feel somewhat intimidated at car shops and I want to know what to say when I talk to the service writer. thanks!
