Car Script Not Letting User Enter?

The car script prompt's the user to buy the gamepass, but if the user own's the gamepass, it won't let the user use the car still. Output show's no error. Can anyone tell me what is wrong with it?

gamepass = 174856301
Check = {}



wait(0.1)
Blacklist = {}
GroupID = 0
seat = script.Parent
cur = nil
script.Parent.ChildAdded:connect(function(it)
        if it:IsA("Weld") then
        tempcur = it.Part1.Parent
        if cur ~= tempcur and cur ~= nil then tempcur.Humanoid.Sit = false return end
        if cur == tempcur then print("same guy!")return end
        print(tempcur.Name)
        done = false
        cur = tempcur
        local Player = game.Players:GetPlayerFromCharacter(cur)
        for _,i in pairs (Check) do
            if i == game:GetService("MarketplaceService"):PlayerOwnsAsset(Player,gamepass) then
                done = true
                if Player.PlayerGui:findFirstChild("Car") then
                    done = false
                end
            end
        end
        for _,i in pairs (Blacklist) do
            if cur.Name == i then
                done = false
            end
        end
        if done == false then
