Here's a two-week alternative, which could include a few car days in southern Spain near the end of your trip: Start in Barcelona {two days}; train to Madrid {five days total, with two days in Madrid and three for side-trips to Toledo, El Escorial, and Segovia or Ávila}; train to Granada {two days}; bus to Nerja {one day, could rent car here}; both Ronda and Arcos for drivers, or just Ronda by train {two days}; to Sevilla {drop off car, two days}; and then train to Madrid and fly home.
