Grab it. That's a good price for a camera with lens.
If the curtain has only a few wrinkles, that should not be a problem. I have a P with Mark Hama at the moment for CLA, with a badly wrinkled shutter curtain. Mark tells me that he can replace the curtain with a fabric curtain, if he can't locate a suitable replacement for the original curtain. So, long term, maintenance should not be a problem.
Have you handled a known-good P before? Check that all shutter speeds sound reasonable, and run a roll of film through it to check that the film transport and re-wind is ok. Assuming these check out ok, and the viewfinder and rangefinder are good, this could be a bargain! Check the lens carefully for any signs of haze, scratches (especially the rear element), and oil on the aperture iris blades.
Even if you don't decide to keep it, there will be people lining up here to offer to take it off your hands!
