I know, it could be, I really dont understand why someone would do that unless there's a problem somewhere, like I say, if there is, why not just spend the money on getting it fixed then you know it's fine, instead of getting another the same but knowing nothing about it.
The only thing I can think of, is that the one he's selling's got quite a big fmic and wondering if the front beam's been cut away, because if has, the front will cave in in a bump....I'm probably talking bollox though, and it's problems somewhere else
