“I am not an attorney, so take it with a grain of salt. Some points:
- The Seller, was he aware that his car had problems and did not reveal at sale？
- Do you have any proof of No 1？
- Did you ask the seller about the problems the car has, in writing？
- Did he conceal the defects knowingly, in spite you asked in writing？
- Why didn't you take the car to a mechanic for evaluation？
- Did the Seller give you any written warranty with the purchase?
If not, when you buy a used car, it is “as is” and you have no claims. It is your responsibility to verify the condition of the vehicle before you buy.“
