This is the company I used for liability insurance: ADA VIS Global Enterprises, Inc. P.O. Box 744 Temecula, CA 92593 800-909-4457 From what I understand you can get insurance for yourself (Drivers License) and operate any vehicle in Mexico or you can insure your bike, but your restricted to driving that one vehicle. Not sure about collision insurance, I didn't get it. Cost was $83 for one year. For Medivac I used: http://www.geosalliance.com/medivac-tsandcs.html I used this discount code "EOY2011MV" for an additional $20 off. I think I paid $89, I think it has now gone up to $109 for a year. It is the same company I have Search and Rescue coverage through ($12/year). http://www.geosalliance.com/sar/index.html You can buy short term policies for either one, but for the small extra amount I got a year (in case I go back ).
