I think you being the only forum member actually working in automotive design, you might be better off doing the initial art work yourself based on what you think a new Wing should look like. Once you get the ball rolling others will come along with input.
Okay, I'll get things rolling. I will start with the front end/wheel. I would like to see (for easier cleaning) either a solid wheel, or a fully enclosed wheel. I would also like to see much wider tires.
I have attached a rough sketch to show the general idea.
