Dash round to get the car (8)
I believe the answer is:
runabout
'the car' is the definition.
(runabout is a kind of car)
'dash round' is the wordplay.
'dash' becomes 'run' (I've seen this before).
'round' becomes 'about' (I've seen this before**).
'run'+'about'='RUNABOUT'
'to get' acts as a link.
(Other definitions for runabout that I've seen before include "Small light vehicle" , "small aircraft" , "little motor" , "nippy car" , "mini perhaps" .)
