Its just like buying a house: Would you buy a brand new house for $500k, or a old period home that is a but rundown for $500k?
You can move straight in to the new home, and have no issues for sometime, whereas the old home will need some renovation and require ongoing repairs.
But, in 20 years time, the new house is now an old house, and the old house is still an old house. Yet the original old house is now worth more than the 'newer' old house.
I'm not trying to cast an opinion here, but people have a strong preference for one or the other, with no in-between. Only you can decide what YOUR preference is.
...OK, I throw i my view. I'd take 3 or 4 1970s EM machines. They look nicer!
