You might consider combining an independent visit to Athens with an organized tour to the archaeological sites and places of historical interest in the Peloponnese and Delphi. Here is a listing of some of the tours available: http://www.grecian-tours.com/countries/GR/
Or consider following one of the tour itineraries in your own car. You'll save money and travel at your own pace.
Athens is best savored at your leisure, definitely without a car. Pedestrians are advised to exercise extreme caution when crossing streets.
Many years ago, before we began writing travelogues, we took driving trips throughout the Greece mainland. These were our first European travel experiences, in an completely different era in Greece's evolution. Even though they are dated, you may find some useful info in our Greece travelogues.
