Business ProfileforImpex Auto Sales

I purchased the vehicle without financing and after washing it at home, discovered a 2' ***** in the bottom of the driver's side rocker panel. I called the dealership multiple times but they would not connect me to someone to talk to. I ended up driving there and proposed trading the car back for another on the lot with myself paying the difference. I was told this was not possible and they could do a trade in at $32,000, a $5,300 difference from the purchase price before tax/tag/doc fee. I asked for this to be printed, which he did, but quickly walked away with it.I informed them that I called a few Tesla certified body shops and was told this was a $10,000 - $16,000 repair as the damage was close to the battery, which would have to be removed before cutting out an entire quarter panel, welding a new one in, and then painting. I informed the manager that this was greater than 25% of the cost of the vehicle, no damage waiver was signed, and asked if there was anything he could do. He offered $500 more to trade but informed me the car is worth 30k but he's throwing in 2. 5k in to help me out. This conversation was audio recorded.I signed an arbitration agreement at the time of sale. I have photos of the damage existing on the car prior to sale from an **** listing from the dealership with the *** number. In the photo the wheels are heavily damaged, however they were clearly repaired prior to me seeing the vehicle. Additionally, there is touch up paint covering some areas of the ***** along with various other areas of the car. Per NC law, damage over 25% of the cars value must be disclosed with a written and signed statement. This was not done. I would like to either exchange the car for one that's not damaged or would like the dealership to give me contact information for who to name in arbitration, they have failed to do so despite multiple attempts over phone, website chat, email, and LinkedIn.
