MEX is the largest car rental company in Mexico. Every step of the renting, picking up, and returning process was very smooth, professional, efficient, and accurate. I bought the QEEQ Super Peace of Mind full insurance (insured by a domestic insurance company). The rental company didn't make things difficult for me or recommend any additional insurance. There is a MEX shuttle bus outside the airport. Every staff member was serious and responsible, with a very good attitude. We arrived at the rental hall at around 3:30 p.m. There were four counters open, with two customers waiting ahead of us. I waited about 10 minutes to start the process, which took around 10 minutes. Picking up and inspecting the car took about 10 minutes. Overall, very satisfied.
