How to get the rotation?

local currentShelfPos = script.Parent.Parent:GetPrimaryPartCFrame()
		print(currentShelfPos)
		local X = currentShelfPos.X
		local Y = currentShelfPos.Y
		local Z = currentShelfPos.Z
		script.Parent.Parent.Parent.Parent.AvailableCar[btn.Text]:SetPrimaryPartCFrame(CFrame.new(X,Y,Z))

So this bit works so far, it puts the car in the same position as the other car, How would I make it have the same rotation?

Thanks
