After 3 days without internet connection, the system and reservation server are back!!
We are experimenting a few problems with the reservation engine in our web site (we are trying to fix it as soon as possible), and we are working to make the web site back to 100%100 current day.
If you need price list for a car hire please send an email to firstname.lastname@example.org, with the details of the rental period, group type and any extra information that may help us to give the better price.
Thanks for your understanding.
