Trying to make car float (making hover car)

im trying to make a hover car. at the moment i just want it to float really but i can’t get it to float at all. the gravity keeps pulling it down.

		local function makecar_float()
			local grav = workspace.Gravity
			local totalmass = 0

			makecharMassless(true, c)

			--calculate total mass of car
			for _, instance in ipairs(zalek:GetDescendants()) do
				if instance:IsA("BasePart") or instance:IsA("VehicleSeat") or instance:IsA("Seat") then
					totalmass += instance:GetMass()
				end
			end

			for _, car_part in ipairs(zalek:GetDescendants()) do
				if car_part:IsA("BasePart") or car_part:IsA("VehicleSeat") or car_part:IsA("Seat") then
					local gravity_force = totalmass * grav

					local vf_attachment0 = Instance.new("Attachment", car_part)
					vf_attachment0.Name = car_part.Name.."_VFatt0"
					local vf_attachment1 = Instance.new("Attachment", car_part)
					vf_attachment1.Name = car_part.Name.."_VFatt1"

					local vectorForce = Instance.new("VectorForce", car_part)
					vectorForce.Name = car_part.Name .. "_vf"
					vectorForce.Attachment0 = vf_attachment0
					vectorForce.Attachment1 = vf_attachment1
					vectorForce.Force = Vector3.new(0, gravity_force, 0)
				end
			end

			zalek:PivotTo(CFrame.new(0,50,0))
		end
