Never hesitate on a deal like this. The owner could die, he could sell the lot, somebody else might see it and buy or steal it. Then you'll be kicking yourself for years (ask me how I know). Go knock on the door and be polite and say that you were interested in the bumpers and wondered if he would part with them. If he say, "Hell, you can have the whole damn thing" then grab it or work it any way you choose but don't go in with a low-ball until you feel him out or he may never respect you enough. JMHO.
