Extended warranty might not be a bad idea. But def don't purchase for the dealer. I've seen price quotes for roughly half that. Do some research online. I don't remember the site but better prices are out there for the same warranty.
Edit: found the site that I have heard good things about...
This is one of the first things I'm doing to my SHO, besides tinted windows, when I pick it up in a couple weeks.
Are the badges like most others and just stuck on with glue?
I've debadged all my vehicles. Gives it a cleaner look, IMO.
