I found a video of a 2013 Charger being upfit by "Starcar". Looks like it arrived as the least-equipped police package and was upfitted aftermarket.

The negatives I see in this upfit are a lot to do with how it will perform in a collision, and how it will wear in rust-belt climates. To the latter, they drill holes and don't appear to seal the metal before sticking things through the holes, no paint or anything. There are a LOT of holes too, so I can see a lot of possible rust points.
To the former, the airbag disconnect switch seems necessary given the laptop mount, and that whole thing seems like a potential issue. In the front, when they install the pushbar they left off the factory under-bumper-cover reinforcement relying entirely on the aftermarket outer reinforcement.
How does this upfit compare with the corporate-supported upfits done on the Charger?
