Total mispurchasing

I bought a car in the market,unfortunately without a purchase contract because it was a well-known one from a friend, who besides his main job also has a workshop and there builds and sells cars.When I picked up the car, I noticed on the way home that the cooler balance tank is broken, I had it repaired,and I was told the cooler pump was leaking, again the seller built me at his expense a supposedly new one. next is I burst the cooler hose, so I paid again, then I raised summer tires where then the workshop told me that both were ripe at the back just before bursting. of which I bought the car knew that I am mom and need a safe reliable car, he played with my life and the life of my child, can I take legal action against him????
