Some expensive car -- target when upwardly mobile in this? (3,4)
I believe the answer is:
rat race
'this?' is the definition.
The definition suggests a singular noun which matches the answer.
'some expensive car target when upwardly mobile' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'when upwardly mobile' says the letters should be written in reverse (in a down clue, letters go up).
'ecartar' is hidden in the letters of 'expensive car target'.
'ecartar' reversed gives 'RAT RACE'.
'in' is the link.
Can you help me to learn more?
(Other definitions for rat race that I've seen before include "Working life's struggle" , "The struggle to get on in life" , "Grim struggle" , "day-to-day struggle" , "nine-to-five" .)
