Bodyside moldings
I ordered a set for my 2010, but have not had a chance to put them on yet. I also bought a set from them for my kid's mini cooper. They are an almost exact match in color. The local dealer asked where i got them so he could start selling them.
The only thing with these moldings is there are no instructions or templates to line them up on the doors. You need to measure, remeasure, tape off and stare at them with the car on a level surface to make sure they are straight and follow the line of the car. The mini took about an hour start to finish. I expect the challenger will take about the same.
