She's nearly 11 years old now and the handling doesn't feel especially sharp - I appreciate these aren't race cars but it feels a bit tired on the road and almost disconnected, more so at the rear end. The kind of feeling that can only be described as the wheels shiftying around under the body. Is this just common worn bushes or joints? Or are there any other mounts or anything I should concentrate on? All looked ok and nothing popped up on the MB health check (which surprised me as if there was an issue, I would guess they'll find it no matter how small!) Many thanks.
