A convertible mustang is a thing of beauty that much cannot be improved upon, except the type of top. A hardtop convertible is a step up for any car but would make the mustang even better. Not only is a hardtop more aesthetically pleasing but it is also a stonger, more durable option and also provides for a better ride with the top up. A function where the top could be retracted manually as to save energy from the battery would be a plus.
