The old model made by Ford even now (3)
I believe the answer is:
yet
'even now' is the definition.
(I've seen this in another clue)
'the old model made by' is the wordplay.
'the old' becomes 'ye' (resembles a historical spelling of 'the').
'model' becomes 'T' (Ford Model T car).
'made by' is a charade indicator (letters next to each other) (letters written or made by another set of letters).
'ye'+'t'='YET'
'ford' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for yet that I've seen before include "Still; nevertheless" , "Still, even" , "Though; still" , "Up till now" , "Up to this time and continuing" .)
