You gonna be able to inspect it before you commit to buying it? And, by that, I mean take it down? There may be rust on the inside of the walls that you can't see until the liner is removed. I'd hate to see you plunk down your money because the pool looked good on the outside and then find out once it was yours that the walls were rusting.

(When I replaced a liner in one of my pools several years back, the walls looked fine. But, once the liner was removed, I found rust.)
