SIXT is, by far, the best rental car facility in Cabo. We have been using SIXT for several years after being burned by several other companies for our earlier visits to Cabo. There are no 'surprise' tactics with extra charges like many other rental places in Cabo. Just get the insurance you need. It is not forced upon you. They even stayed open past their closing time just for me because my flight was delayed 3 hours - AND texted to make sure the shuttle was there to greet me.
Marcos is absolutely fabulous in terms of customer service and Victor was a delight as my shuttle driver and very heavy suitcase lifter. We own a rental property in Cabo and recommend SIXT to all of our guests who want to rent a car.
