Faulty Car

Be Careful with these ones I bought a vehicle at Hatfield rivonia and collected the car on the 06 of April we drove the car from Johannesburg to Cape Town on the car the fuel reported that it had about 500 km on the tank, we drove all the way to Colesburg with the car and when we got there it sill had about 200 km of fuel that is half a tank we poured fuel and it amounted to R856 which does not make any sense, the car stalled on the 23rd of April and started misfiring, the engine light was on and the EPC light was on, we towed the car it still had 200 km of fuel, after the diagnosis was done it was found that car had an empty tank, and that the car was damaged underneath and the fuel lever was damaged beyond repair, this was not disclosed to me when I purchased the car and there is no way I can check a car for underneath damage when buying
