If you have a red interior, a set of black mats is a good idea. My dealer kicked in the Z8 satin cover. Its also a good idea to carry a quart of the Z8 motor oil (BMW/Castrol 5w30) with you as these engines will "eat" a little oil- all M engines have this trait. FYI, other things I carry are a cigarrette lighter type air pressure inflator and a tire pressure gague--- and a radar detector!
