Actually, inventory searches are kind of fun in a suppression motion.  Generally they only note the contraband, so you start asking for the contents of the car that they were so concerned with safekeeping and they are often not listed, which makes it not an inventory search but rather a search for evidence with no exigency and thus requires a warrant.  Motion to suppress granted; motion to dismiss granted.  Course the defendent has already been to jail, hired a lawyer or gotten us appointed and its bee a pita at a minimum, but its good fun for the lawyer.
