It's not a car show but, it'd do alright if I put in the back window! This is a common question but, there is no rule against it. The lexan I made for it needed some better fitting and it helps to have two people when installing. I'll get around to it eventually but now the focus is on racing /supporting the class. The car needs things for improvement here and there so, any abundance of time I have I'm spending on that list first.
