Just a small note about power windows. I believe that they actually weigh less than a manual crank window because a window motor is lighter than the metal crank mechanism.

And arguments aside, since I'm joining this conversation late and haven't read the whole thing.
If someone is offering me MSRP then he's doing me a favor, I don't care if he does or doesn't know about the vehicle. Isn't that basically it or did I miss something?
