that's not the same. I ask you to buy that stuff for me because
a - it isn't available here
b - you don't attend fleamarkets so you cannot chase down old loose cars for me.
I could care less about pictures of new cars because there is no excitement in finding them unless they're pretty limited, and even so you can see pics of them online (errors, hush, you're the exception). It's another matter altogether when someone finds an old car, be it in minty condition or in beat up shape, because there is something you can appreciate, and that is precisely it's condition.
With a supermarket car, well of course it's new, you just opened it, I can go and see mine if I want to see one. Yet with an old car the condition you found it in is what makes it fascinating and interesting to see, from "omg that's mint as hell" to "yeah that'll buff out with a hammer".
