Not transparent upfront in ads

Dealer was not transparent in pricing upfront and conduct. Did not disclose in ad that a mandatory warranty must be bought for R12 000 extra, and also additional out the door admin fees of another R7200 ! When I said his price was too high and way above market, he told me the retail price of the vehicle was R185 200 while I had 2 independent industry valuation reports that had the retail value between R118 000 and R144 000. When I showed him one of the reports he dropped his price in the add quickly the next day with R20 000 without informing me.

I left a negative review on AutoTrader but he complained to them and **** to them about what really transpired to have it removed. I have all whatsapp communications saved with proof of everything this dealer said.
