Good luck on you're purchase! Ether color would be great but I would go with the Nightfall Gray tho I may bias. You should be able to get the GM Supplyer discount more info about that can be found with a simple Google search and GM offers a $1k conquest discount you should be able to get because you are switching from a BMW. Both discounts are available and can stack but it is up to the individual Dealership if they will honor ether discount or not.
