Hi Ridergraphix and welcome. I love your sight, I think I may have even posted a link on a older topic.
My biggest suggestion would be to make a carbon fiber "look" vinyl hood stripes. Many people will be interested in that look as it was on the concept and production 08 SRT 8.
Some other ideas:
[ul]
[*] `Cuda decals
[*]T/A stripes (see
http://www.ridebuilder.com/rb/fun/ch...erPainter.html)
Kowalski or a Vanshing Point decal (maybe with his outline of Kowalski's face or his name, a small depiction of a chally outrunning a police car(s), or just the words vanishing point)
[*] Challenger SS decals
[*] Hemi, Challenger, or `Cuda Scuff plates and engine covers.
[/ul]
On your website, if you would just alter most of the decals of the charger to fit the challenger, you would really be in business.
The old Challenger script will be pleasing to many so having that as a option for vinyl choices would be great.
Also, while this may not be used on the Challenger, a road runner decal (assuming you can get the necessary papers, if any are needed) may interest some Charger or Ram owners.
Whatever you decide, I cant wait to see what it looks like.
