I applaud your want to get in on the small details, but honestly, the Durango Hellcat will sell itself. It will have a large price, so your target market is not going to be of the upsold into it/cross-shopping variety. Anyone who has the genuine interest and credit score to qualify for the vehicle is likely going to very well understand what they're looking at (and are likely there for that car).
The only selling you'll have to do is if your dealership does the smart thing and places something like a 10-20k dealer added markup on it. They're only making these for 1 year and in small quantity. Almost all of them are customer orders, so to have one of the few unspoken for on your lot will no doubt come with a hefty dealer markup. If it doesn't, you're leaving money to rot on the vine.
So, if it were me, I would play the whole, "Yes, this is a genuine Durango Hellcat" card. And, when it came time to negotiate, as the sales manager, I wouldn't. "We're sorry, but the vehicle is exceedingly rare and in very high demand. We have a premium on the vehicle for this reason. If you're well qualified, we may be able to get some special financing considerations, but for the near future, the price is firm."
And, if your dealership has any web presence whatsoever, so long as it isn't marked up to stupid, it'll sell in a week or two with a 10-15% added dealer markup to someone who has to have one but couldn't order one before they closed the banks out.
These Durangos are literally selling used 15-25k over MSRP on eBAY right now (most are classified used, but with only 12-20 miles). Folks are simply buying them, then relisting them. One private seller has sold 5 of them in the past 2 weeks.
