sports-cars

I'm a little stuck... Click here to teach me more about this clue!

'vehicles' is the definition.
(sports car is a kind of vehicle)

'display marks of damage' is the wordplay.
I cannot quite understand how this works, but
'display' could be 'sport' (to sport an item is to wear or display it) and 'sport' is found in the answer.
'marks' could be 'scars' ('scar' can be a synonym of 'mark') and 'scars' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
