Hire limo primarily wanting comfort (5)
I believe the answer is:
lease
'hire' is the definition.
(I've seen this before)
'limo primarily wanting comfort' is the wordplay.
'primarily' indicates taking the first letters.
'wanting' means one lot of letters go next to another.
'comfort' becomes 'ease' (easing is a kind of comforting).
The initial letter of 'limo' is 'l'.
'l'+'ease'='LEASE'
(Other definitions for lease that I've seen before include "Charter" , "Term of a rental contract" , "Summer's has too short a date (Shak.)" , "Property rental agreement" , "Contract for use of land or building" .)
