Get rid of the subheadings, except for things that aren't scooters, like ATVs and Motorcycles. Too much gets overlooked by people who know how to solve problems because the guy who used to own a Yager isn't looking in the Yager section anymore, and the guy who owns a Like 150 used to have a Super 8, and knows a lot about it, but isn't looking in the Super 8 section. I guarantee you the interaction will improve overnight.
