Historic racing car (7)
I believe the answer is:
chariot
'historic racing car' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I don't see?
This is the entire clue.
Can you help me to learn more?
(Other definitions for chariot that I've seen before include "Roman two-wheeled vehicle" , "Haricot (anag)" , "Two-wheeled carriage of ancient times, as used by Ben Hur" , "Horse-drawn racing vehicle; oat rich (anag.)" , "Two-wheeled horse-drawn vehicle used in battle" .)
