Why won't my car change CFrames?

Hello everyone, I'm currently trying to set the CFrame of a car with a VehicleSeat. However, whenever I attempt to set the CFrame, the car always glides back to its original position.

Local:

currentRC = game.ReplicatedStorage.Init:InvokeServer(mouse.Hit)

Server:

local function deploy(plr, pos)
	if plr.Character:FindFirstChild("E-RC") then
		local c = target:Clone()
		c.Parent = workspace
		c.Main.CFrame = pos
		return c
	end
end

game.ReplicatedStorage.Init.OnServerInvoke = deploy

Everything is welded to the BasePart named 'Main'

Thanks in advance!
