Hi. It's based 100% on the Keaton car, but it order to keep mine road legal using existing lighting, a few modifications have been made. I did have large wheels and tires donated, but they are for show only and not driving as the weight of my modifications have lowered the car enough that they cannot be used. AND every single 2 inch screw that is in the Batmobile was in my Shuttlecraft and will live there forever. Its amazing how much that shuttle has gave itself towards other projects. OH, and the car is as big as it physically can be so it can be removed from the lawn and still fitting between the fence posts. At 6.5 feet wide and 19.5 feet long, it aint tiny.
