In May of 2016 we were in Toronto, Canada for he birth of our granddaughter. Our son had sold his car so we Ubered everywhere on his account and found it to be a fantastic and very economical service.
In Toronto you have to have a cell phone to use Uber and I do not know if that is the case here.
I do have friends who have used Uber here and have been very happy with the service.
Here is how you can contact the Uber Service here in Ajijic, Lake Chapala: 331 702 1932 or 332 177 0018.
