I just spent $25 and had some custom vinyl "automotive stickers" made online. The company I used (Banner Buzz) had an online tool - I made a "sticker" with UV protection 3.75x240 inches long. I didn't bother to try and strip off the old residue. I figured for $25 it was worth it to see how it looked. The top stripe had basically flaked off with time, so I just stick the new pieces on over where the old was.
After spending hundreds of hours meticulously redoing the interior, it's weird that I would go the "cheap" route - but in this case, I'm happy.
You'll note the bottom edge isn't perfect. This is because when I ordered the sticker I neglected to leave a space above and below for the imperfect cutting system - so the cut on the vinyl wasn't very clean and it obviously shows. But, knowing that I could strip it off and try again lets me not worry.
