If you’re looking to rev an automatic car, there are a few things you need to know. First, the car needs to be in good condition - it should be clean and free of any chips or dents. Second, the engine needs to be running properly - it should be cold and have no oil or grease on it. Third, the transmission needs to be in good condition - it should be smooth and not sticking. Finally, the brakes need to be in good condition - they should be strong and not giving out easily.
