Anything I need to know about this car from you vet's.
I will be trading in a 2004 BMW M3

Are you crazy? Your gonna trade an 04 M3 for a Navigator? I like Navigators, dont get me wrong, but come on, its a freakin' M3!!! That Navigators a BIIIG car. Good luck finding a normal parking space, and parking it! But other than that, its a great car.
