I'm a total newbie to the Forum and to my 2005 BMW Z4 E85 3L roadster. It's got 89000 miles and seven owners who were not old grannies. I have been repairing bottom broken plastic skid plates but some seem to be missing including the small cover (6 in X 6 in or so) for the oil change. I need a service manual. How can I get a service manual? How many bottom plastic/metal skid plates should be down there anyway?
