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
