Character stole awfully large car (7,7)

I believe the answer is:

chelsea tractor

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

'large car' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'character stole awfully' is the wordplay.
'awfully' is an anagram indicator.
'character'+'stole'='characterstole'
'characterstole' is an anagram of 'CHELSEA TRACTOR'.

Can you help me to learn more?

(Another definition for chelsea tractor that I've seen is " Huge 4WD".)

I've seen this clue in The Telegraph.
