The problems with suspension is with pretty much all "newage" models, (bugeye, Blobeye, and Hawkeye shapes) from 2001 onwards... there would appear that the quality of the rear shocks are not up to standard, and its common that they have to be replaced on warranty. some have reported having to have them replaced multiple times, there is however, apparently a new shock that is supposed to stop these problems happening... but I don't know much about that.
the common thing, I think (as I drive a classic), is a Knock when you are pulling away from traffic lights... if you are in any doubt, I'd recommend that you take the car to an authorised dealer to get checked, as your car fits in to that age bracket...
And "member scooby222" is no "Scoobie master", he just enjoys a spirited drive in the countryside... as do we all...
