Highly recommended! If you're looking to rent a car in Nuevo Laredo, come here to Sixt (1203 Benito Juárez Av.), the staff are friendly, professional, and accommodating The prices are reasonable, and they have a nice selection of cars. I rented an economy car, a Chev Aveo. It was very clean, in great shape, drove really smooth, really strong a.c., and great on gas. I drove from Nuevo Laredo to Monterrey and back on one tank of gas, basically. The car drove great, no issues. I had a nice trip. I didn't pay extra for the mileage; I used around 400 kilometres, which was included in the rental price.
It's great if you're just walking across the border into Nuevo Laredo; it's a 10-minute walk from the border. Just book a few days ahead. Overall, it was a great car rental experience; it was easy, fast, and very welcoming. I'll definitely rent from them again. THANKS! Peter B.
