IMO the Crossfire is what it is, a Chrysler Crossfire. It is not a Mercedes Benz.
It is sold through Chrysler dealerships. It is not sold (new) through Mercedes Benz dealerships.
How many S-Type Jaguars have been rebadged as a Ford Lincoln, or X-Type Jaguars rebadged as Ford Mondeo? None?
Leave it as a Crossfire or debadge it but don't rebrand it.
The majority of the public out there know what a Mercedes Benz is but they rarely recognize the Crossfire.
Doesn't it make you feel good when they ask "What's that you're drivin' mate?"
