Get a PPI done even if you are buying the car from your mother or brother - it will save you big headaches down the road if they catch something and it will give you piece of mind. They should scan the car for the code(s) and be able to tell you exactly why the SES light is on. Mileage, year and price all seem to be legit but make sure you get a PPI
