I purchased my Redline Red Vapor in February 2015. The banks were closed at that time. They may or may not open in the future.
750 Red Vapor Package editions were made when the bank was open.
I was able to find my vehicle by going through the listed vehicles on the Jeep Website by narrowing the options.
I looked yesterday and found one still available in Grapevine, TX. I didnt look through all the inventory on jeep.com
New 2015 Jeep Grand Cherokee For Sale | Grapevine TX
It might not be available since the window sticker will not pull up.
I would think there are not many left at dealerships.
I purchased mine 380 miles from my house.
