New rating's hair in excellent condition (5,2,4)
I believe the answer is:
right as rain
'excellent condition' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'new rating's hair' is the wordplay.
'new' is an anagram indicator.
'ratings'+'hair'='ratingshair'
'ratingshair' anagrammed gives 'RIGHT AS RAIN'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for right as rain that I've seen before include "Perfectly fit and well" , "In perfect order!" , "Very fine" , "perfectly in order" .)
