Thanks for your reply mate, didn't get any manuals with the car is there maintenance needed on the suspension, only one suspension fluid tank I assume which fluid is required to top up Is there anything that needs replacing on the suspension over time??? Not over familiar with the hydractive suspension Just seems to roll excessively even at relatively low speed's (30mph) I have to use the armrest to keep myself upright never experienced anything like that before, and have driven many cars and vans, especially bad when going round a right corner. One of the reason's I bought a C5 is my boss has one and it has done 140,000miles and it seems to handle alot flatter it's 1.5years newer but otherwise identical to my knowledge
