I like the subtle stripe on the RT, not a fan of the louvers or the matt roof look. The claw marks would have to go. For me less is more on my vehicles.
Yeah, the R/T stripe is okay, probably better on a lighter colored car. I could like with the matte black roof but lose all those louvers, they look tacky. The matte black roof sort of simulates the vinyl tops of the 60's and 70's, a lot of Challengers had them. It needs a a piece of chrome trim to break up the hard paint line of the two colors a little better. That flexible plastic chrome trim is stocked at local part stores.
Forget the claw marks; The lower door stripping is nice, but needs to be a contrasting color; I've seen better looking louvers, I had them on my earlier Daytona back when. On today's Challenger that have poor all around driver's viewing, I would stay away from them especially the side window ones; I dislike the flat black roof, looks like a cheapened cover-up. IMO
