Vehicle's part for which you need to pay, very possibly (8)

Ross

I believe the answer is:

footwell

'vehicle's part' is the definition.
(where your feet go in a car)

'to pay very possibly' is the wordplay.
'to pay' becomes 'foot' (as in footing the bill).
'very possibly' becomes 'well' ('well' can mean 'very').
'foot'+'well'='FOOTWELL'

'for which you need' is the link.
