Car_Refund lawyer

Hello, everyone, I bought a used car last year $4000, it is a toyota in 1996. It looks good and drives well, but suddently the mortor is failed, so the car is ready to go. I am considering to sue the last owner, IS IT POSSIBLE FOR ME TO DO IT, WHAT IS THE REASON AND WHAT KIND OF LAWYER I SHOULD CONSULT WITH. I mean this car shouldn't last so short, especially for the motor part, what is your opinion. Many Thanks.
