At the counter, the staff asked us if we wanted to pay extra to upgrade the vehicle. After we declined, their attitude became very cold, and without our consent, they secretly added a so-called road assistance insurance for $106.80!!! When charged, we asked why, and they said it was a deposit and would be refunded when we returned the car. After picking up the car, we asked customer service and found out it was an added insurance!!! What a scam!!! We will never rent from AVIS again! Liars!!!
