993 Rattles

[digdoug993]

Anyone out there got any ideas on why my 1996 C2 is rattling so much. When I leave the gym evryday I have to drive slowly thru this neighborhood and I consistantly here this rattling noise as I go over smaller bumps. A mechanic suggested it may be the center caps but I don't think so...any suggetions on what else to check?
If you could email me at [e-mail] that would be greatly appreciated.
Thanks in advance!
