If the PPI comes back clean, I'd jump on it. And the brake job is a snap...an hour to 1 1/2 tops if you've never done one before. And you CAN do it. Its got fairly new tires, a new rear window, battery, and a few other things. It sounds like a good deal to me. When you see it in person and if its as nice as presented, get the PPI and go for it.
BTW.. those are probably the smallest pictures I've seen.. hard to tell much about it from them
