For my trip to California, I rented a car to get around. Because of my budget, I reserved a car similar to my own (Toyota Corolla). When we got to the rental agent they told me they were out of Corollas, but gave us a Pontiac Vibe instead. After getting to the parking lot we discovered that the Vibe had a dead battery. Then, they replaced the Vibe with a Mustang (for the rate of the renting a Corolla).
