Stolen gun and car (3,3)
I believe the answer is:
hot rod
'car' is the definition.
(hot rod is a kind of car)
'stolen gun' is the wordplay.
'stolen' becomes 'hot' (I've seen this before).
'gun' becomes 'rod' (rod is a kind of gun).
'hot'+'rod'='HOT ROD'
'and' is the link.
(Other definitions for hot rod that I've seen before include "Car radically modified to increase performance" , "Car with souped-up engine" , "Car modified to increase speed and acceleration" , "Car modified for extra power and speed" , "fast vehicle" .)
