Petrolhead short of fuel drove one finally for a spin (7)
I believe the answer is:
hardtop
'petrolhead short' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'fuel drove one finally for a spin' is the wordplay.
I cannot quite see how this works, but
'one' could be 'a' (a thing is one thing) and 'a' is found within the answer.
'for' could be 'to' (eg both can mean 'in the opinion of') and 'to' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
(Other definitions for hardtop that I've seen before include "Rigid-roofed vehicle" , "Sort of car" , "Car's rigid roof" , "Car with a rigid top" , "Non-convertible car" .)
