It's no good without a luggage compartment (8)
I believe the answer is:
bootless
'without a luggage compartment' is the definition.
('luggage compartment' can be 'boot' (synonyms) so maybe 'without a luggage compartment' can be ''bootless')
'it's no good' is the wordplay.
I cannot really see how this works, but
'it's' could be 'es' ('e' can mean 'electronic' which is similar to 'IT') and 'es' is found in the answer.
'no' could be 'o' (resembles 0 - 'no' can mean 'zero') and 'o' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for bootless that I've seen before include "unprofitable" , "unlike puss in Perrault's tale" , "Of little or no use" , "Be so lost (anag) - vain" .)
