It will take you just north of 20 hours to complete, and this Gran Turismo 7 walkthrough can take you through every car unlock required. There are various other things to unlock as you go, such as tracks and one or two of our best cars in Gran Turismo 7, as well as the multiplayer Sport mode. In short - you’ll need to complete the campaign to unlock some major features. As for directions, to complete each Menu Book, cars will be highlighted on the map, and it’s simply a case of ticking off those objectives and returning to the cafe to collect your reward - which is typically a short, sumptuous lesson on the cars you’ve collected, plus the next menu book for you to fill out. Our credits farming techniques can help you then purchase the cars and upgrades you need. Best of luck with the campaign!
