I'm not much of a city person either, but B.A. is worth a look. There are other worthy sights on that side of the continent, too--parts of Uruguay, Iguazu, etc. For nature, mountains, remote places, deserts and such, the west coast is far more interesting. You're not short on time, so inbound via an east coast port and out via the west coast (or visa versa) makes a certain amount of sense. That might end up meaning Valparaiso and Montevideo.
Your original post asked mainly about Ruta 40, so this is all getting somewhat off-topic.
