Bright lights of the city, scenic road trips, or rugged terrains? However you choose to spend your time in Ontario, there’s a reliable car waiting for you at CarRentals.com. Those planning to tick off a lengthy list of sights and attractions should pick an SUV or a full-size car. Prefer to stick around the city? Climb behind the wheel of a compact or an economy ride. After traveling 2 miles from Upland to the downtown area, maneuvering narrow lanes and squeezing into tiny parking spots will be easier with these smaller vehicles.
