Give a car, say to (6)

Ross

I believe the answer is:

afford

I'm a little stuck... Click here to teach me more about this clue!

'give' is the definition.
(synonyms)

'a car say to' is the wordplay.
I cannot really understand how this works, but
'a' is found in the answer.
'car' could be 'ford' (ford is a make of car) and 'ford' is located in the answer.
A single letter 'f' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for afford that I've seen before include "Be able to buy" , "Able to bear the expense" , "Have the financial means" , "Run to" , "Provide; be able to pay for" .)
