German car company (4)
I believe the answer is:
opel
'german car company' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for opel that I've seen before include "German subsidiary of General Motors" , "Car firm with" , "French-owned German car manufacturer" , "German motor manufacturer, 1871-1948" , "German car maker, d. 1948" .)
