Next month my wife and I plan to rent a car somewhere outside Paris (away from traffic in the center of the city) on our way to Giverny, Rouen and Normandy. Where would be a good place to find a car rental close to a Metro or RER station in the Paris suburbs? Regarding a later drop off, it looks like the closest spot after staying in Mont Saint Michel is Rennes, about an hour away by car. Any other ideas on a drop off rental location after Mont Saint Michel?
Also we are both 75. Is there an age restriction for renting a car in France?
