Aim of driver, quite some distance? (7)
I believe the answer is:
fairway
'aim of driver' is the definition.
(driver as in someone driving a golf ball)
'quite some distance?' is the wordplay.
'quite' becomes 'fair' (I can't explain this - if you can you should give a lot more credence to this answer).
'some distance?' becomes 'way' (way is a kind of distance).
'fair'+'way'='FAIRWAY'
(Other definitions for fairway that I've seen before include "Part of golf course between tee and green" , "Golf course area between tee and green" .)
