I have a la marzocco linea (my first coffee machine) that I have been using for a year after buying from a coffee shop in South London. It's an amazing machine in perfect working condition. I had OZONE service the machine last year and replaced a few parts and still pours amazing shots all day!!
More information- new seals, fan, group head seals, la marzocco water pump, alot of the wiring. It's never been de scaled and the elements where checked and is in good condition for the year. The previous owner used a bestmax xl filter for years and I have as well. It comes with original group handles new shower screens. It's ready to go!!!
Hope this answers any question if not email me!!
