Pros: We showed up in Loreto only to find out that there was not a car for us even though we had a reservation. We were one of 10 other travelers stuck in the same situation.
FYI Ace, Fox and Mexcar are all the same company. Do not rent from any of them!!
Cons: Mexican third-party liability insurance is not included in the fees and is required for Mexico, if you don't want to sit in jail while they figure out who is at fault in the accident. It is not covered by your credit card or your US insurance policies either. It is significantly more expensive than renting the car. overall though it was about $350 for a week renting a Volkswagen Jetta.
Cons: I had been quoted online
$55.00 for 6 days. But at the rental I was told I had to take mandatory insurance that brought the charge to $285.00! I felt that was a ripoff but they would not let me have the car unless I agreed. I had no choice. If in fact this kind of insurance cost is required in Mexico, it should at least be disclosed on the website. I have a suspicion though it should not have been that expensive and I got ripped off.
