Fit American President: upfront, sharp, expensively kitted out
I believe the answer is:
well-appointed
'sharp expensively kitted out' is the definition.
I can't judge whether this defines the answer.
'fit american president upfront' is the wordplay.
'fit' becomes 'well' ('well' is associated in meaning with 'fit').
'american' becomes 'a' (common abbreviation - e.g. in organisation names).
'president' becomes 'p' (common abbreviation eg in VP).
'upfront' becomes 'pointed' (I can't explain this - if you can you should give a lot more credence to this answer).
'well'+'a'+'p'+'pointed'='WELL-APPOINTED'
Can you help me to learn more?
(Other definitions for well-appointed that I've seen before include "Properly supplied" , "Fully equipped" , "(Of room/building) finely fitted-out" .)
