Get better sort of truck (4-2)

I believe the answer is:

pick-up

I believe this is a double definition.

'get better' is the first definition.
(pick up can mean to improve or get better)

'sort of truck' is the second definition.

(Other definitions for pick-up that I've seen before include "Light open lorry with low sides and a tailboard" , "Collect; casually acquire" , "Improve, increase" , "Small truck or lady met informally" , "Recover" .)

I've seen this clue in The Telegraph and The Times.
