The pick-up and drop-off process was very simple and convenient. However, there was no electronic toll card, and the first time I encountered a cash only toll lane on the highway, I missed it. When I returned the car, I hadn't received any toll information yet, so I'm not sure how long it will take to charge my credit card. Also, since I was unfamiliar with the nearby gas stations and worried about refueling too early, I opted to let the rental company fill the tank and pay the fee. The service fee of $1 was acceptable, but they charged me $4.8 per gallon, which seemed too high for Chicago compared to the $2.5 I saw later in Dallas.
