Considering buying a refurbished La Marzocco Linea Classic 3 Group EE as my first machine for a new coffee shop

Hello fellow Redditors.

Big time lurker here and aspirational barista/coffee shop owner. I’d like to know and would appreciate your opinions on if this machine is a good purchase and option for a beginner barista and someone that is trying to open up their first coffee shop. I know a little bit about La Marzocco but again this would be my first machine in which I would train and ultimately use it for a cafe.

Seller is wanting $4000 for this refurbished La Marzocco. They say it’s completely refurbished, boilers, gauges, etc. They are also offering 3 month warranty and installation thrown in that price.

Anything I should look for ? Would I be regretting my purchase if I go with this machine or is it a steal ?

Please share your thoughts and TIA.
