They require you to buy insurance, and you can't pick up the car without it. Furthermore, if there are any issues, they make it difficult to dispute. I showed two credit cards, and they deliberately chose the one that had been active for less than a year. When I complained to the car rental platform, MEX Rental Company ignored my complaint citing a credit card discrepancy. So, if you choose MEX Rental Company, you need both courage and luck!

They couldn't find my booking.

They always try to upsell you on renting a more expensive car. When that didn't work, they made me buy a full tank of gas. I felt embarrassed and bought it, which turned out to be a scam because you can't return the car with an empty tank. However, I'm used to being taken advantage of in Mexico.

Service was a bit strange. Representative at the desk told us that as soon as he saw us, millenials, he knew we wouldn't be giving him any commission. Also, they give you the car absolutely empty of fuel and there is no fuel station around. They know it's impossible to bring back a car empty so they make profit on the fact that people bring back the car with fuel in it...

Cheap options which is great.

Be very careful of their tricks to sell you upgrades. They said they would fill in full tank of gas for a cheaper rate than outside fuel stations, they said that fuel level is very low and they suggest taking the initial full tank fuel package. I declined this package, when I get to the car I rented, the fuel is already at full level.
