It's all about the grin factor. 1700km on the bike and I'm yet to pull off my helmet without a giant smile on my face. The most fun I've had behind the wheel was a quick fang of my friends dc5r. Loved the harsh suspension, feeling every bump in the road, but still nowhere as much fun as leaning out with your head cocked at 60 degrees.
Everyone wants to own a sports car, after all wheres the fun in owning a car if you don't have to wrestle it around corners? To each their own and all that. But still, exotics are pretty boring, they were designed only with a lap time in mind.
