Having company, I take new cars around the island (7)
I believe the answer is:
corsica
'island' is the definition.
(Corsica is an example)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for corsica that I've seen before include "Island north of Sardinia" , "French island in Med" , "Mediterranean island, birthplace of Napoleon" , "French island off W Italy, birthplace of Napoleon" , "French territory" .)
