Dont look after interest of their customers

I bought a car from dealership (second hand) , i got finance from above mentioned company. R80k<br> <br> Why dont you look after the interest of your customers , or is it just to make money and we must cover the bills .<br> One year later i wants to trade in the car , they next dealer told me that the car , according to the VIN number was previously damaged to the amount of R 80k , SURELY THE BANK MUST HAVE PICKED THIS UP.<br> <br> Now i cant sell or trade the vehicle and must still pay the remainder installments , now the next question why do you support corupt dealerships , and how many other consumers must also step into that trap
