With Avan Guard we suffered a bad experience hiring a 7 seater Toyota Prado with driver for the four of us for 5 days. The driver was fine but the management continuously misled us. Initially they sent a 5 seater to pick us up due to a mechanical problem with the Prado. They only agreed to replace it the next day after much phoning and insisting we give $50 to pay for the petrol to swap the cars between Goris & Yerevan. At the end of the 5 days although we had left Yerevan with an empty tank they wanted us to leave the Prado full. After nearly an hour on the phone we insisted that we would not pay more than another $50 which represented enough fuel to cover over 1600 kms when we had only done 1000. Not to be trusted.
