Thanks for your comments. I purchased a black with cream interior. I have the luxury navigation package. I live in Florida and while I know that they are just trying to give me a sales pitch, the one comment that made me think about buying the warranty is that the heat could make the nav system have issues down the road. They likened it to my cell phone being left in a hot car for a long time. I garage the car at night but during the day it is mostly out. Is it true that i don't have to buy it right now and can buy it any time before the regular warranty expires?
