Beetle car parts shop's opening on Autobahn (6)
I believe the answer is:
scarab
'beetle' is the definition.
(scarab is a kind of beetle)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for scarab that I've seen before include "divine thing once" , "Holy beetle" , "Dung beetle - ancient Egyptian cut gem" , "Old abuse" , "Beetle, sacred to the ancient Egyptians" .)
