Pale blue Toyota model scratching parking sign (8)
I believe the answer is:
aquarius
'sign' is the definition.
(I know that Aquarius is a sign)
'pale blue toyota model scratching parking' is the wordplay.
I cannot quite see how this works, but
'blue' could be 'aqua' (aqua is a kind of blue) and 'aqua' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for aquarius that I've seen before include "Eleventh sign of the Zodiac" , "Sign of the zodiac, the water-bearer" , "Star sign" , "A 23 ac" , "Sign of the water-carriers" .)
