The bus is an attractive option, however, for me, it is the freedom and spontaneity factor.

Thanks to all for your input.

We have rented in various parts of Mexico with varying success, any guidance for Zihua would be helpful, I have activated auto messaging, TY

Your direct messaging is not set up, so I’ll be brief and discrete publicly. I have rented from pretty much all of the standard big companies at the airport over the years. I have found the quality to be highly variable based on the individual I was dealing with.

In recent years I have rented from Jonny Rumba at Jonny Ca$h, just outside the airport entrance. I have found him to be above board. No surprise fees. I tell him well in advance what my driving needs will be and he has provided a suitable and serviceable vehicle.

I note that the link on Rob’s site is broken.

We had a car in Zihua for a while but sold it. Too many crazy drivers around and the parking is difficult. Having someone else do the driving has the additional benefit of letting you enjoy the view enroute. We hired Pedro Moreno to do the driving. He is honest, responsible and speaks perfect English. 011-52-1-672-119-2398 or pedro.91477@gmail.com

Last Jan/Feb, during our 6 weeks in Zihua, we spent $1000 Canadian on taxis. We're thinking of driving down this coming season, (it would be our 9th or 10th time driving down), recognizing that, over- all, driving is much more expensive than flying.
That said, your comments on the "cons" of driving ones vehicle in Zihua are accurate. Still.....

If you activate your direct messaging on this board, I’ll let you know my experiences with car rentals in recent years.
