BodyForce Not Working! I hope this question is concise enough for this website?

I'm just trying to get my "Car" moving with body force, here's the script

local CarSpeed = 5
local CarAmount = 1
local CarCanMove = true
local function spawncar()
	local Car = game.ReplicatedStorage.Cars.Car
		local TempCar = Car:Clone()
		TempCar.Name = "TempCar"
		TempCar.Parent = workspace
	for x = 1, CarAmount, 1 do
		TempCar:MoveTo(Vector3.new(-0.6, 980.178, -10.6))
	end
end

--[[local function movecar() DON'T MIND THIS PART
	for x = 1, CarAmount, 1 do
		spawn(function()
			local tempcar = game.Workspace.TempCar
			local Pos = tempcar.Primary.Position
			local velocity = Vector2.new(CarSpeed, 0)
			while CarCanMove do
				print(tempcar.Primary.LookVector)
				wait()
			end
		end)
	end
end

movecar()
--]]
spawncar()

wait(5)
local TempCar = game.Workspace:WaitForChild("TempCar")
look = TempCar.Primary.CFrame.lookVector * 500000000
print(look)
TempCar.Primary.BodyForce.Force = Vector3.new(look)

This is the script to just see if the car moves forward, but it's not working or moving, I doesn't have any error messages. But there is this error message which I think doesn't have to do with anything
