Irvine BMW This was a demo just to prove to Irvine BMW and Shelly Automotive Group that I could create a car builder/customizer. They wanted the ability to change the color and interior of the car at the least. This would have been a base build with the option of being able to customize more of the vehicle with additional add ons for a phase two type of project. Since this was only a demo to showcase talent, the Z4 Roadster is the only car that you can actually customize. This would have been a hybrid site consisting of html, asp and flash.
