The first car had issues with its lighting system, which we discovered ourselves and returned to exchange. After driving the second car for nearly an hour, we received a call informing us of a problem with the vehicle and asking us to return to exchange it or to have it replaced at our destination. When I asked about the issue, they wouldn't tell us. For safety reasons, we returned the car to exchange it again. On the phone, they promised a better car, but it turned out the engine had problems, and they gave us the same model again. It's really irresponsible and frightening in hindsight. Luckily, we made it back. Our destination was far, and if something had happened, it would have been a disaster. Their service was average, they didn't inform us of anything, and the return location was not clearly explained.
