|Mar 2023My representative Shora and her supervisor offered me a car that had prior damage. They took pictures of the damages. When I returned the car, the sales rep pointed out that no documentation of any damage had been recorded. I then had to explain that I didnt damage the car and had to show evidence. I had pictures of the damage on my cell phone. I would like the team to follow up and communicate about cars they issue out that have prior damage/dents.
