It's kind of like how the Challengers were about a month ago. There were a couple usually posted each week at MSRP that people could jump on if they wished but they'd be gone in a flash. So it is possible to get a Charger at MSRP but it's not easy by any stretch!
OP I can offer this advice, don't just hang around in the Hellcat Purchasing section of this forum. There was a Charger at MSRP that was posted in the Charger Hellcat section recently and it went under the radar for like a day (hey that's an eternity in Hellcat terms!!) before someone snatched it up.
