Car close to black sedan crashed and turned upside down (9)
I believe the answer is:
ransacked
'turned upside down' is the definition.
(both can mean searched frantically)
'car close to black sedan crashed' is the wordplay.
'close to' says to take the final letters (the close/ending of).
'crashed' is an anagram indicator.
The final letter of 'black' is 'k'.
'car'+'k'+'sedan'='carksedan'
'carksedan' with letters rearranged gives 'RANSACKED'.
'and' acts as a link.
(Other definitions for ransacked that I've seen before include "Plundered" , "Pillaged" , "Rifled" , "rifle in the past" , "turned upside down?" .)
