Luxury car departs, lacking nothing, for city (7)
I believe the answer is:
limoges
'for city' is the definition.
(I have seen 'City of porcelain' mean 'limoges' so perhaps 'city' could also mean 'limoges')
'luxury car departs lacking nothing' is the wordplay.
I cannot really see how this works, but
'car' could be 'limo' (limo is a kind of car) and 'limo' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for limoges that I've seen before include "French city known for its porcelain" , "French commune" , "French porcelain centre" , "foreign city" , "French city noted for enamels and porcelain" .)
