From economy models to luxury vehicles, SIXT has it all. Our fleet is filled with a variety of car categories to choose from, including sedans, SUVs, minivans, pickups, sports cars, convertibles and passenger vans. When you rent a car in California, you can also choose some bookable extras to further customize your experience, such as an additional driver or child seats. While a one-day rental is a convenient option for a beach day, a weekly rental is a good choice if you will be going on a longer road trip.
