Saving models in dataStore?

Title says it all. I haven't tried this, because i know it will end catastrophically. Here's what i think it would look like:

local Save = {}

game.Players.PlayerRemoved:connect(function(player)
    table.insert(Save,1,game.Workspace:FindFirstChild("Model"...player.userId))
--It's a building thing where everything the player places get's put onto their model.
end)

But will it save the Positions and Colors correctly? I mean, will it add to the table correctly, and then save correctly in a datastore. Will this work, or do i need to get the values of position and color for all the parts?
