Regen Dilemma, can it be fixed?

 I have a new vehicle regen that is designed  not to regen the vehicle if the vehicle is in use. However, when the vehicle is legitimately regenned the vehicle disintegrates to its most basic parts. How can I fix this so the vehicle can be regenned to its original structure rather than fall apart? Here is a copy of the regen script.

local Vehicle = script.Parent.Vehicle:Clone()

for i, v in pairs(Vehicle:GetChildren()) do
	if v:IsA("Script") then
		v.Disabled = true
	end
end
local CurrentVehicle = script.Parent.Vehicle

local Regen = script.Parent.Regen
local ClickDetector = Regen.ClickDetector
local Display = Regen.Display.Label

local InUse = false
local Debounce = false

function UpdateUse()
	Display.Text = Debounce and "REGENERATING" or InUse and "VEHICLE IS IN USE" or "REGEN"
end

function HandleVehicle(vehicle)
	InUse = false
	local seats = {}
	
	local function CheckUse()
		local used = false
		for i, v in pairs(seats) do
			if v then
				used = true
			end
		end
		InUse = used
		UpdateUse()
	end
	
	local function GetAllSeats(vehicle)
		for i, v in pairs(vehicle:GetChildren()) do
			if v:IsA("VehicleSeat") or v:IsA("Seat") then
				table.insert(seats, false)
				local id = #seats
				v.ChildAdded:connect(function(child)
					if child.Name == "SeatWeld" then
						seats[id] = true
						CheckUse()
					end
				end)
				v.ChildRemoved:connect(function(child)
					if child.Name == "SeatWeld" then
						seats[id] = false
						CheckUse()
					end
				end)
			elseif v:IsA("Model") then
				GetAllSeats(v)
			end
		end
	end
	GetAllSeats(vehicle)
end

HandleVehicle(script.Parent.Vehicle)

ClickDetector.MouseClick:connect(function()
	if not InUse and not Debounce then
		Debounce = true
		UpdateUse()
		CurrentVehicle:Destroy()
		CurrentVehicle = Vehicle:Clone()
		CurrentVehicle.Parent = Workspace
		for i, v in pairs(CurrentVehicle:GetChildren()) do
			if v:IsA("Script") then
				Delay(0.1, function()
					v.Disabled = false
				end)
			end
		end
		HandleVehicle(CurrentVehicle)
		wait(5)		
		Debounce = false
		UpdateUse()
	end
end)

 Currently, I use the old person299 regen. Besides the fact that the vehicle can be regened right out from under you, the regen works great. Here is a copy of the person299 script if it can help.

--Edited Button Regen Script by Person299
system = script.Parent
local c  = system:GetChildren()
for i = 1,#c do
a = c[i]
if a.Name ~= "person299" then
if a.Name ~= "put in only 1 model" then
model = a
end
end
end
backup = model:Clone()
regen = system:findFirstChild("put in only 1 model")
function checkRegen()
if regen.Value == 1 then
if(model.Parent == system) then
model:Remove()
wait(1)
end
model = backup:Clone()
model.Parent = system
model:MakeJoints()
end
end
regen.Changed:connect(checkRegen)

You can't compare "and" to a string, it doesn't know what the string means.
