Roll over a Dutch car (8)
I believe the answer is:
roadster
'car' is the definition.
(roadster is a kind of car)
'roll over a dutch' is the wordplay.
'roll' becomes 'roster' ('roster' can be a synonym of 'roll'**).
'over' indicates putting letters inside.
'dutch' becomes 'd' (common abbreviation).
'a'+'d'='ad'
'roster' going around 'ad' is 'ROADSTER'.
(Other definitions for roadster that I've seen before include "Old car" , "sporty vehicle" , "Small open-top car" , "sporty car" , "Open two-seater car" .)
