Whats wrong with building it the way you want it and use it for what the car was made for ??? i done an underbody resto on mine and since its been finished ive been out in it the whole time... dont see the point in spending huge money on the best of everything and then leave it in a bubble or in a shed for the rest of its life... i take it you wont use it in the rain so alls thats gonna happen is a couple of chips to the paint that no one will ever see and abit of dust underneath... not the end of the world in my eyes
