Michael, the tint angle (for father/son debates) is that it helps preserve the interior from UV fading etc (I live in the desert and that's a major reason for it). That gives it a practical angle. Plus it is good for security since people cant see inside as easily to see what you got in there.
I'm all about great deals on wheels - sounds like you got that. Beggars cant be choosers and in a way it's nice (for me) since I wouldn't be able to decide on a particular wheel to get if I just went out and bought new stuff (it would cause weeks of sleepless nights).
