Day late and dollar short: My vote would have been, and indeed is still for my car: the OEM light gray thing. The yellow sounded pretty cool, I'll admit. And remember, this is second tier stuff we're talking about here. One does not run around w/ the bonnet up, I am thinking. Unless one is called Hoopty, in which case just about anything could happen. Still, it is nice to look in there from time to time, and may as well have it look nice. The practical aspect here would be to have a color upon which any leak would be seen right away -- thus putting black or other dark color at a disadvantage. Just 2 cents worth. So there it is: a dollar short and $0.02 in; still $0.98 down . . .
