That Peugeot looks super! Good job!

Honestly, I can make my own graphics but I think 40 bucks for a set is a bargain. I'm playing with inkjet waterslide decals now, not sure how well they'll hold up. I also have an ALPS, but haven't used it in a few years; its capable of fabulous results, though now long obsolete.

If you can create the vector art going to a sign shop that prints and cuts vinyl is your best bet. Colors are limited to what they have as it uses a thermal transfer process, so Pantone is not going to help much, but they can print on white, clear, gold, silver, foil, whatever, and cut to a specific shape if you define it with a vector line. They charge by the size and number of colors, so a single set might run less than 40. if you can create the art. But print a few and sell them to help recoup your costs...
