Itís not just advertising. Itís bekow-the-line PR and having an owners magazine etc which come with having enough sales. Alfa lost their magazine and finished with the Cloverleaf Club years back. With new models comes coverage from spy scoops to road tests and vloggers.
Having the two models and genuine halo models of each has helped but there is nothing to report on compared to the competitors and their constant feed of new cars.
