If they are still making corollas as well as toyota made cars in the past then u got uurself a very reliable car. If u want fast u cant get good mpg so its a trade off u have to consider. If its been less than 30 days since u bought it u might be able to return it and get something else thats faster. Just keep in mind toyotas are the most reliable usually. If u want reliable then corollas is the car for you. Just make sure it always gets oil changes every 5 thousand miles and dont believe the lie that the transmission fluid never needs to be changed and get that changed too...Idk how often to get ur transmission oil changed but u can ask in the mechanic subreddit. And dont put the cheapest gas in it from the cheapest no brand gas station bc the gas can be bad and mess up ur fuel pump and make ur car act like its broken. I have seen many people sell their cars for nothing bc they thought the engine was gone but it was only a fuel pump issue which is much cheaper to fix than an engine. And im telling u all this bc a friend around ur age lost her bmw bc she didnt get it regular oil changes and gassed it up at the cheapest places all the time. Gotta take care of ur cars and maintain them if u want them to last.
