If there is one of the two that you like better from a color, feature standpoint I would choose that one. I drive an 05 SE and it is a great truck. The 06 would be a great truck also. But, if you buy the 06 because it is newer and you have to get into it every day and hate the interior color or features, you will never be happy with it. If you are keeping the truck for over 5 years anyway, they will both depreciate. I wouldn't let the stereo be a factor...For $700-800 you can put in a nice all Alpine system that would rival the factory fosgate if you wanted to. I don't know of any major issues with these trucks that should indicate you need an extended length of warranty. It is a Nissan...Good luck, I don't think you can go wrong.
