VOETSTOOTS AGREEMENT

On the 6th of April 2009, i purchased a 1998 Toyota Corolla 160i GLE for R36 000 from a place called Ottawa Car Sales (as per a signed Voetstoots contract). I took ownership of the vehicle and paid the owner cash. Upon taking the car for COR on the 10th of April 2009, i was informed that the entire front of the vehicle was welded onto the rest of the vehicle. I feel that this was misrepresentation on the part of the seller, as had i known this, i would not have purchased the vehicle. I have asked the seller to return the amount paid and take back the car. However he has refused. Is there any legal action that i can take to get my money back?
