The expensive car registers (5)
I believe the answer is:
rolls
This clue is a double definition.
'the expensive car' is the first definition.
(short for Rolls Royce)
'registers' is the second definition.
(lists of names)
(Other definitions for rolls that I've seen before include "Turns over - luxury car (abbr)" , "Official lists" , "Moves like a wheel" , "Car - goes with swaying motion" , "Trundles" .)
