3vz-fe v6 3.0 (1992-1993) I have a 92 and it was great. Check the valve cover gaskets for leaks if they havn’t already been changed, the back which you cant see will be worse. Easy and cheap to replace but usually always need replacing. Also ( at least this happened to mine) check the brake lines (metal) under the car and make sure they are in good shape. Mine rusted out and sprang leaks. The needles in the gauges go out or dim, theres some solutions but usually arnt cheap, but also not always a big deal. Theres really not anything major that goes wrong.
Overall its an excelent car, very reliable. If you wanna know more PM me.
