script.Parent.MouseButton1Click:Connect(function(GetCar)
    if tick() - lastime >= 76.4 then
        lastime = tick()
        Mod = game.ServerStorage.Tsar --Change test to whatever you have named the item you want to spawn
        clone = Mod:clone()
        clone.Parent = workspace
    clone:MakeJoints()
    script.Parent.Parent.Parent.Parent:Remove()
