Vehicle likely to show the mark of an accident (6,3)
I believe the answer is:
sports car
'vehicle' is the definition.
(sports car is a kind of vehicle)
'likely to show the mark of an accident' is the wordplay.
I cannot quite see how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is present in the answer.
'mark' could be 'scar' (mark left by an injury) and 'scar' is found within the answer.
'of' could be 'o' and 'o' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for sports car that I've seen before include "Low-slung two-seater" , "flashy motor" , "Lotus perhaps" , "fast vehicle" , "Racer" .)
