Bought a second hand car , damages was withheld

I bought a car from this company who swore that this was a very clean accident free car an year ago for R 80, 000. Now that i want to do a trade in , we discover that the car was actually in major accident , repair costs were what i paid for it R 80,000, now i'm stuck with the vehicle and cant get rid of it. In this past year i had to replace the starter, clutch and damper pully , not even to mention the services to the amount of R 20,000, <br> I feel badly ****** , how can they do business like this. Till now they still says its a clean cars , (but they them self does not want to give me a trade in )
