Monito,
those machines are fine. I suspect this beast is a LOT worse inside than yours or Milo's.
For that price... I think i wouldn't.
Machines like that are sand on the beach. You/he can definitely do loads better.
Check the year, with maintenance de facto age does not matter. BUT if it didn't receive any the timeframe is enlightening.
That machine looks a little older. End of the 90s is my guess?
Regards,
Felix
