How to I make it where people cant spam the Gui Text button to spawn cars?

I am working on a game on roblox and i notice that some people spam the button to spawn tons of cars and then it starts to make the game laggy because they cars are spawning inside each other. Can someone help me make it where they cant spam the text button. This is the script to make the car spawn and check the price. Btw im a noob on coding lua scripts.

script.Parent.MouseButton1Click:Connect(function()

if script.Parent.Parent.Purchased.Value == true then

-- Spawn it

game.ReplicatedStorage.SpawnCar:FireServer(script.Parent.Parent.Name)

else

--Let them purchase it

local PriceOfItem = game.ReplicatedStorage:WaitForChild("CheckPrice"):InvokeServer(script.Parent.Parent.Name)

if game.Players.LocalPlayer.leaderstats.Cash.Value >= PriceOfItem and script.Parent.Parent.Purchased.Value == false then

-- The player has enough cash

game.Players.LocalPlayer.leaderstats.Cash.Value = game.Players.LocalPlayer.leaderstats.Cash.Value - PriceOfItem

script.Parent.Parent.Purchased.Value = true

script.Parent.Text = "Spawn"

end

end

end)
