The name of the dog in the car? (5)
I believe the answer is:
rover
'the car?' is the definition.
(former British car manufacturer)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for rover that I've seen before include "Nomad" , "Car - dog" , "Wanderer, rolling stone" , "Pirate; dog's name" , "Wanderer, archery mark" .)
