I can help you with a couple of the questions. The warranty would be 6 months of the refurbished model. The grinder is quiet when compared to many others on the market, I would give it a 5. As what the machine will come with. It will be just the machine, it depends on what we have, but it may be missing the scoup. Things it won't come with are the water filter a new one comes with, brew group grease and a bottle of descaler. As for the age of the machine, I cannot be certain on that.
