Racing vehicle kept for sale? (5,3)
I believe the answer is:
stock car
This clue might be a double definition.
'racing vehicle' is the first definition.
(I've seen this before)
'kept for sale?' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
Can you help me to learn more?
(Other definitions for stock car that I've seen before include "Vehicle adapted for bumping races" , "production saloon" , "Production vehicle used in racing" , "Production-line vehicle modified for racing" , "Type of racing" .)
