Also, not only Honda, but almost all of the Auto Manufacturer websites suffer from over-engineering. They use alot of java, asp's, graphics, etc which take a lot of server and network resources. Most of this is dictated by their marketing and ad agency's. If they would just stick to simple HTML, JPGs and Frames, they could provide much responsive info without causing their customers to suffer through the glitz.
I have a friend who is responsible for a couple of auto manufacturer websites, and there is a team of people iinvolved with the design of a site. They have to figure out how to add all the site features, like build your own car, etc, and keep the speed up.
