Pair touring Canada wrecked Bobby's vehicle (5,3)
I believe the answer is:
Here is my best explanation:
'bobby's vehicle' is the definition.
(term for a police car)
'pair touring canada wrecked' is the wordplay.
'pair' becomes 'pr'.
'touring' means one lot of letters goes inside another (touring can mean going round).
'wrecked' indicates anagramming the letters.
'canada' is an anagram of 'andaca'.
'pr' going around 'andaca' is 'PANDA CAR'.
(Other definitions for panda car that I've seen before include "One patrolling", "Something with copper inside?", "Police vehicle", "station wagon?" and "In official vehicle".)
