Old Ford carrying it into city (5)
I believe the answer is:
osaka
'city' is the definition.
(Japanese city)
'old ford carrying it' is the wordplay.
'old' becomes 'o' (abbreviation).
'ford' becomes 'ka' (the Ka is a type of Ford car).
'carrying' says to put letters next to each other (in a down clue, the bottom letters carry others).
'it' becomes 'sa' (SA can mean sex appeal, as in 'it').
'ka' after 'sa' is 'saka'.
'o'+'saka'='OSAKA'
'into' acts as a link.
(Other definitions for osaka that I've seen before include "Major port and commercial and industrial centre on Honshu" , "Third most populous Japanese city" , "Japanese port city" , "Port city on Honshu, Japan" , "Kinki's capital" .)
