Get a mechanic to look over it, because even though it's your friend, there might be a chance there's something wrong with the car (that both of you don't even know about), and you don't want to feel like he ripped you off if later down the track something happens to it that neither of you could foresee.
Also, drive it yourself first (if you haven't), because you'll regret buying a car that you don't even enjoy driving later on.
