cable

I'm a little stuck... Click here to teach me more about this clue!

'kind of car?' is the definition.
(I've seen this in another clue)

I don't understand the rest of the clue.

(Other definitions for cable that I've seen before include "Telegram; wire rope" , "Communications wire" , "Rope for communication" , "Telegram; thick rope" , "Strong thick rope made of twisted hemp or steel wire" .)

I've seen this clue in the Evening Standard.
