*********... Think again before buying from them

I recently bought a VW Polo from their Durban branch I was told that the car was accident free... A few days later I noticed that the front of the car had been repainted, I had no problem with that, beacuse I thought it was cover up for the wear and tear from the previous owner. I had the mishap of s****ping my front bumper against a wall and had no problem the follwing days, the car drove without a problem... Aboua a week later my car stars leaking coolant from the cooling system. I then send it to KIA to have it checked out. I am then informed that the minor accident caused damage to my radiator and I am told mumbo jumbo about my headlight being losse from that, and then they ask me if I had taken the car to someone to have it fixed!!? They say the tech who was inspecting my car is the same tech who inspected it before I had perchursed it and he never made any weld to the vehicle meaning I had done that!! That got me thinking if I was sold a car that was involved in an accident... I no longer want this vehicle and I'm considering legal action because I never tried to cover up my dents, and just a scratch to the bumper wouldn't normally cause this much damage..
