So I went through this thread and suddenly found myself back in the early '80s when I was 25 with only one difference....I owned a Renault 5 TL at that time.
It was painted like a piece of candy which was inspired by a car that was build guy named Sbarro, so I recognize the urge to want to be different then all the rest and commend you for your tenacity.
Here's a pic of that car:
Of course almost no one is going to like what you are doing to the car as it doesn't fit into today's standards but hey.....it's your car right?
I wish you all the best with your project and hope the bill will not pull you over every 10 minutes when you are driving it because that is probably going to happen as soon as you hit the streets.
