We booked a gasoline car but were given an electric car, a Ford Mustang Mach-E. We were told that for cars under two years old, charging is free. We thought we'd give it a try. The car was new, with just over 1000 kilometers on it. Charging had its challenges; without a U.S. phone number and Apple ID, we couldn't download the charging app. Some fast-charging stations accept credit cards, with a $50 pre-authorization each time. Even a week later, we haven't seen the actual charges, so there are four $50 authorizations, with actual charging costs varying from $20 to $30 each time. Charging did bring some hassle; we had to wait about 30 minutes to an hour each time, and some charging stations require the app to use, making finding a charging station a concern during our trip. Thankfully, everything went smoothly, and we made it to our return destination. In San Diego, we received a 'head-in only' parking ticket, which was missed in our research on car rentals in the U.S., so we remind everyone to watch for head-in parking requirements. Fines for parking violations must be paid as instructed. We followed the appeal instructions but received no response. Contacting the car rental customer service about the charging fees wasn't helpful; we had to contact the charging stations' service numbers ourselves.
