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..

This car does it all. It’s perfect for the weekend, the daily ,the snow, the rain and it’s pleasure to get in every day. Will probably own this one for the long haul.

2018 was a good year!

I have owned two earlier versions of this model and two other models from Audi and I am blown away by this car’s newer levels of luxury, fit, and finish! The newer features and amenities are quite nice too! The virtual cockpit and massaging seats are amazing! I am still learning the vehicle so I’m sure some things are being left out!
