The problem is so widespread they'd be ill advised try to hold a lessor responsible. They couldn't get away with it.
I personally don't think the paint should be a deciding factor in whether to lease or buy; there are more important financial [and other] considerations.
I wasn't aware of the paint issue when I signed, so it had no bearing on my decision.
Since I'm leasing, I really don't have any skin in the game so I don't care about it, but if I had bought, I'd be pissed.
Look around the parking lots some more. See it for yourself. You may find that it's not as serious a cosmetic problem as some would lead you to believe. Then again, I imagine the severity varies widely.
