I was over charged for gas that I was told I didn't need to replace. I was charged $47 almost $48 for less than 6 gallons of gas. I filled the gas 2 days prior to returning the car and it cost me $29 to fill. So I don't know why I was charged so much for so little gas. So to answer the question of if I'll recommend you to a friend. Lol hell no not after you rip me off
