After looking at the price difference between the Honda roof and the Direction 2 roof, I went with the Direction 2 roof.
The Direction 2 roof was less than half the price of the Honda and it fit with the Genuine Honda windshield. Installation was easy even in below freezing November weather. Material quality, fit and finish was top notch. I would certainly buy other Direction 2 accessories. The Direction 2 roof looks much better on the P500 in real time. The Direction 2 ad picture does not do the view justice. I will likely buy the Direction 2 rear window in the coming year.
