Audi A3 bought from Infinity Auto

I bought a second hand Audi A3 form them and 3 days later the car broke down due to missing bolts on the left CV. I approach the dealership and they told me sorry they cannot do anything for me and they also admitted to me that they don't check the vehicle for road worthy, nor did they advise us that the vehicle are being sold as is, jet they managed to register the vehicle within 30 min. The Audi A3 was also listed as R 79 950.00 with new BBS mags (fully loaded) and tyres and only after I told the sales person I will take the car was I told that I needed to pay R 10 000.00 extra if I want the BBS mags and new tyres I will never buy from them again as they are just out to take your money
