Many folks ask me about renting a car in Mendoza. This is of course possible, but there are a number of drawbacks.

First, rental costs in Argentina are high when compared to other countries. Signage in Mendoza is rather ackward, and distances from winery to winery is sometimes important. Dont think Napa where everything is close and signage is perfect... Mendoza is big, there is a lot of new development and even the locals arent the best for directions, things are changing very quickly. Plus, if you really want to enjoy your wines, its a bad idea to get behind the wheel.

Renting a car with a driver or a van if you are in a small group is the best way to go. I will dig up a few contacts and post more information later.
