$390 is alot of money to put down on a rig and damage like that is not repairable.I would be more than perturbed to pay for plane tickets and a hotel and find damage like that.
I have inquired on a number of rigs at PPL. On one, also rated excellent, the pictures on the website carefully avoided the substantial staining on the ceiling where there were very bad leaks. It two weeks of bugging the sales person to finally get the honest pictures. Very disturbing and as far as I was concerned, misleading.
