Superior passport perhaps found in Russian vehicle (2-2-2)
I believe the answer is:
la-di-da
'superior' is the definition.
'passport perhaps found in russian vehicle' is the wordplay.
I cannot really understand how this works, but
'passport' could be 'id' (a passport is identification) and 'id' is found in the answer.
The remaining letters 'lada' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for la-di-da that I've seen before include "Informally, having affected manner of pronunciation" , "Stuck-up" , "Hoity-toity" , "Pretentious, snobbish" , "I'd a lad with affected manner or pronunciation" .)
