My wife and I used Fred and Karina for our recent trip to Buenos Aires, and I echo all of the previous recommendations. Fred was waiting for us at the arrivals area at EZE, even though our flight was early. He offered us a free loaner cell phone (we just paid for the minutes) and offered to exchange money for us at the going rate so we didn't have to deal with the money changers at EZE. On our drive into town he offered a number of useful tips on things to do and see during our visit. When we arrived at our apartment, the rental agent was late and Fred waited for 20 minutes until he showed up so we didn't have to sit on the sidewalk with our luggage. Karina picked us up to take us back to EZE at the end of our stay, and we received the same excellent service. If you're looking for a classy, reliable, premium car service in Buenos Aires, you won't go wrong with Fred and Karina at Silver Star. www.silverstarcar.com
