Yesterday I purchase...

Yesterday I purchased a i10 Hyundai took it for a test drive it was ok the only issue was clush, on my way home it died on me, I think it was the oil, I did explain to them that I'm not experienced when it comes to cars, saw the oil light coming on, it was at night in the free way when I called the sales man he said I must call a tow truck and pay for it myself, I feel that they knew the problem with the car and they let me take it on top they threw their contract in my face plus there are not papers yet
