So, you are thinking about adding some graphics to your car. The first thing you need to consider is what you want. Some of the striping options are (in approximate order of cost); pin stripes, single colour stripes, multi coloured stripes, and partial vehicle wraps.
You can also put window bands, logos (such as the Chevy Bow Tie, or Dodge Ram Head) on your car or truck.
It is a good idea to look at other cars like yours to see what they have done to theirs. A common statement that we hear is "I want to put a stripe on my car, but I don't know what I want." In order to narrow your choices down, it helps at least to eliminate some catagories, such as flames.
There are some good web sites for getting ideas, such as this one. Since we can print our own graphics, we can take those ideas and design a graphic that is uniquely you.
