After your Challenger is built at Brampton, ON, it must be trucked 3 hours west to Windsor, OH (Upfit Center) for the stripes. If you are lucky, you will get your car in a week or two. A lot of us, however, had to wait almost one month AFTER the stripes were applied. It seems that Dodge likes to place the completed cars in storage while they await full shipment loads.
Good luck. No matter how long the wait, it will be worth it!
