The Progressive coverage in Mexico is something you have to talk to them about and read how it is written. We were charged $10 a year for ALL of our coverage in Mexico except liability. When we read the fine print, they had restricted us to 10 days a year in Mexico. Another phone call, and we had it changed to 6 months with no additional charge.
To my knowledge, all of the providers of Mexican liability insurance raised their limits January 1 of last year to cover the higher limits.
