Citizen.CreateThread(function()
    RequestModel(npcHash)
    while not HasModelLoaded(npcHash) do
        Wait(500)
    end
    npcPed = CreatePed(4, npcHash, npcCoords.x, npcCoords.y, npcCoords.z - 1.0, npcHeading, false, true)
    FreezeEntityPosition(npcPed, true)
    SetEntityInvincible(npcPed, true)
    SetBlockingOfNonTemporaryEvents(npcPed, true)
    while true do
        Citizen.Wait(0)
        local playerPed = PlayerPedId()
        local playerCoords = GetEntityCoords(playerPed)
        local npcCoords = GetEntityCoords(npcPed)
        local distance = GetDistanceBetweenCoords(playerCoords, npcCoords, true)
        if distance < 2 and IsControlJustPressed(0, 38) then

            local vehicleModel = GetHashKey("12charger")

            local vehicle = CreateVehicle(vehicleModel, -149.93916320801,156.19316101074,76.93675994873, GetEntityHeading(PlayerPedId()), true, false)
            SetEntityVisible(vehicle, true, false)
            SetEntityCollision(vehicle, false, false)
            NetworkSetEntityInvisibleToNetwork(vehicle, true)

            TriggerServerEvent('oxi:showroom:getData')
        end
    end
end)

This is what i have.
