That is a very good idea, a convertible Malibu! I love the way that you did the windscreen, I saw something like that the other day and really thought that somebody should implement that type of feature (raw glass edge on top) in a production vehicle. and of course, as Phoenix mentioned, Suicide doors are always great!
I would say that would be a good challenge to the sebring convertible but since a one eyed monkey with pencil could design a better car than the sebring, I will simply say good job! I could see that cursing around Hawaii or wherever with a family in aloha shirts within.
