DataSave not saving at all?

Hello. I am making a datasave which saves two (or more) bool values in the player in CarStats. I have two datasave scripts in the game one for money and one for cars (this one). It does not work and i need some help. I try it online in a roblox server and on solo but it still does not work. CarDataSave Script:

local dataStoreService = game:GetService("DataStoreService"):GetDataStore("Earth2DataStore")

game.Players.PlayerAdded:connect(function(plr)
    local key = 'id-'..plr.userId
    local stats = Instance.new('IntValue',plr)
    stats.Name = "CarStats"
    local CamaroOwned = Instance.new('BoolValue',stats)
    CamaroOwned.Name = "CamaroSSOwned"
    local LamOwned = Instance.new('BoolValue',stats)
    LamOwned.Name = "LamborghiniOwned"


    local getSavedData = dataStoreService:GetAsync(key)
    if getSavedData then
        CamaroOwned.Value = getSavedData[1]
        LamOwned.Value = getSavedData[2]
    else
        local saving = {CamaroOwned.Value, LamOwned.Value}
        dataStoreService:SetAsync(key,saving)
    end
end)

game.Players.PlayerRemoving:connect(function(plr)
    local key = 'id-'..plr.userId
    local save = {plr.CarStats.CamaroSSOwned.Value, plr.CarStats.LamborghiniOwned.Value}
    dataStoreService:SetAsync(key,save)
end)

As you can see it saves two bool values in the player so it knows if the player owns the car. I really need help with this i have been trying to do this for months now. Remember i have tried it in a server! Please help!
