Correct , it's either working or spares or repair .I thought dealers couldn't use the sold as seen get-out-of-jail card? Everything they sell has to be as described and fit for purpose.
I'd ask them to repair the leaking ram and sort out the grab, as both render the machines unfit to use. A dealer who values his good name wouldn't mind doing so at the cost of a few quid. If nothing else, he'd want you to feel you could buy from him again in the future.
