Terrible experience! Thank God we saw the Carfax

Be awared on this 2018’ Audi S4! I wanted to buy it out right to the dealership! I don’t finance cars, but wow look at the Carfax report and look that on 11/23/2021 damaged reported minor damage. Damage to left front!!! Ok strike #1 .... Then 05/28/2022 Porsche Chantelly, Va reported miles 71,446 miles and then 12/15/2022 Indiana Motor Vehicle Dept Libertyville, IL odometer reading reported 90,105 miles!! In 7 months someone drove the S4 and put 18,659 miles???? strike #2.... Then look at the end of Carfax report 03/01/2023’ Structure Damage another accident!! Gish terrible... No wonder in 03/03/2023 the S4 was $30,995 and now $26,987.. I was going to buy it and give then a certified check buying out right, but No freaking way. I ask the Saleman questions about the history and then talked to the Manager and they started to stutter and I was told call Carfax report! I told the Manager thanks God we look at the Carfax Report and someone is getting screwed On this sale, but it won’t be me!!! I hope people realize you are getting screw on this S4, but sure someone will fall for it because of price..
