Overpricing *******

In bought a 2022 Toyota Hilux as a "Demo" model with 19 000km of which I have come to learn that it was never a demo but regardless of them being dishonest about this, they sold me the Hilux for R 655 000 with a balloon payment of R 200 000 (Raider, Double Cab & Manual) of which I have now come to learn that a brand new 2023 model like mine from the floor of Toyota will cost R 602 000. Now that I want to trade it in the vehicle I'm at a shortfall of R 200 000 and I'm told that I will be stuck with this Hilux until its completely paid as no dealership will over me more that R 450 000. I would not recommend buying from them as they only want to push profits into their own pockets and have no care about client satisfaction.
