My wife and I did a Euro driving trip just over a year ago. Our plan was we had no plan. We carried my laptop which was loaded with Microsoft Autoroute, and connected it to a Garmin handheld GPS. I kept the auto-routing feature set to avoid highways and tollroads. Each morning we would decide where we wanted to go, plug it in to the PC and then roll. Worked great. Begin at Paris Charles de Gaul, to Burgundy region of France, across the Jura mountains into Geneva. North from Geneva through Basel into Black Forest region of Germany, to Stuttgart (Porsche Museum, of course), to Baden-Baden, to Strasbourg, back to Paris.

I would get yourself some sort of mapping software like autoroute. It will help you plan an itinerary, and give you a sense of how much time you will spend behind the wheel from point to point.
