Mixed collection of great style in sports car going to Spain (7)
I believe the answer is:
melange
'mixed collection' is the definition.
(I've seen this before)
'great style in sports car going to spain' is the wordplay.
I cannot quite see how this works, but
'style' could be 'elan' ('elan' can be a synonym of 'style') and 'elan' is present in the answer.
'car' could be 'mg' and 'mg' is present in the remaining letters.
'spain' could be 'e' (abbreviation for Espana) and 'e' is located in the answer.
No letters remain.
This may be the basis of clue (or it may be nonsense).
'of' is the link.
(Other definitions for melange that I've seen before include "Miscellany" , "Gallimaufry" , "mixed collection" , "Varied mixture" , "A French mixture of me with angel" .)
