How would you make this regen unanchor the model?

I don't know if this will completely work, I think it will.

script.Parent.Parent.Name = "CarRegen"
local everything = {}
local names = {}
local children = game.ServerStorage:children()
local debounce = false
local ChangeColor = true -- true = changes colors; false = doesn't change colors.
local NameOfPartsToColor = "ChangeColor" --This is where the name of the parts you want to change colors goes.

for i = 1,#children do
    if (children[i].Name == "Car") then
        table.insert(everything, children[i]:clone())
        table.insert(names, children[i].Name)
    end
end

function unanchor(Model)
	local ThingsToUnanchor = Model:GetChildren()
	for i = 1, #ThingsToUnanchor do
		if (ThingsToUnanchor[i]:IsA("Part")) then
			ThingsToUnanchor[i].Anchored = false
		elseif (ThingsToUnanchor[i]:IsA("Model")) then
			local TTU = ThingsToUnanchor[i]:GetChildren()
			for i = 1, #TTU do
				if (TTU[i]:IsA("Part")) then
					TTU[i].Anchored = false
				end
			end
		end
	end
end

function ColorCar(Model)
	if ChangeColor then
		local ThingsToColor = Model:GetChildren()
		local Color = BrickColor.random()
		for i = 1, #ThingsToColor do
			if (ThingsToColor[i].Name == NameOfPartsToColor) then
				ThingsToColor[i].BrickColor = Color
			end
		end
	end
end

function regen()
    for i = 1,#everything do
        local new_thing = everything[i]:clone()
        new_thing.Parent = game.Workspace.CarRegen
        new_thing:makeJoints()
		unanchor(new_thing)
		ColorCar(new_thing)
    end
end

script.Parent.ClickDetector.MouseClick:connect(function()
    if not debounce then
        regen()
    end
end)
