Back in my impressionable days, I had a 1987 purple Z24 Cavalier and thought it would be cool to have neon under lights. Installed them myself only to find out I drilled some of the screws that hold them in place, directly into the gas tank. Took it for a spin and noticed my gas gauge dropping quickly. I got out, looked under the car and what do you know, gas is pouring over the glowing neon lights.
lack of brain cells can account for actually wanting them on my car and the installation.
