The right rental decision at San Francisco International Airport depends on where the itinerary goes after pickup, not on a generic -best car- label. Start with the airport transfer, then list passengers, luggage, parking needs, road conditions, and any toll or charging questions.
A city-only plan puts garage dimensions, hills, and parking cost ahead of cargo volume. Napa, Monterey, and Peninsula itineraries add road shape, luggage, tolls, weather, and charging or fuel planning to the vehicle decision.
Compare the agency's current vehicle description and terms with the actual route before booking. Treat rates, authorization holds, hours, inventory, and add-on policies as changeable: verify them with the operator and the relevant airport or transportation authority immediately before travel.
