I can completely understandable your having more than one Busa. I've been considering buying another and parking it in my living room just so I have something to admire and watch during the commercials!
Seriously, with the value of the Dollar crashing overseas, all foreign products especially Japanese cycles will increase in price considerably. Better buy now if you think you want one. They will be much higher and soon. The '07s are a steal if you can find one the right color you like.
