Ok, nobody guessed all of them correctly, but they were
Wheels nuts for hair
The plastic fasteners that hold the front grille on (the ones with the middle that pushes out) were the buttons.The eyes were rubber bonnet stops, the ones that go here
The mouth was the rubber seal like this one
Closest was Kaci, who said interior fasteners for the buttons - the same ones are used to hold part of the centre console in place. When I asked him which fasteners he meant he said the ones in the door panels.
I'll see if I can think of some other coupe based quiz, but mods please lock this now.
Thanks, Joe.
