Turns over flash car (5)

I believe the answer is:

rolls

I believe this is a double definition.

'turns over' is the first definition.
('roll' can be a synonym of 'turn over')

'flash car' is the second definition.
(Rolls-Royce)

(Other definitions for rolls that I've seen before include "Moves like a wheel" , "Small rounded breads" , "Lists of names of members" , "Luxury car - lists of names" , "Baps - posh car" .)

I've seen this clue in The Telegraph.
