I have the exact same P8! My frame is pretty scratched up, it's a 50cm, and it's been converted to a single speed. Here's a picture so that you can see the paintwork details:
I love this bike, but I agree with the other posters that the UO8 has a better frame. If I didn't have such an attachment to the look of the P8, I'd buy the UO8 in a heartbeat.
If you end up buying the P8, and if you're not interested in the owner's manual, I would really love to have it. Or even just borrow it.
