Series 7 in Forza Horizon 5 has arrived. This new season will celebrate the Cinco de Mayo holiday in Mexico and comes with new cards and new challenges. The first week of Series 7 takes place in the Summer, and it includes two unlockable cars via the Weekly Playlist and a Treasure Hunt. So, how can you get the two main rewards this week, plus the other unlockable cars? Let's take a look.

The Treasure Hunt is very simple for this week. As the hint suggests, you'll need a Pontiac Firebird. One car that will work for this challenge is the 1977 Pontiac Firebird Trans Am. Then, record five stars at Danger Signs to unlock the chest. Be mindful, though, that you will want to tune this car and move it to a higher class, like S1. The chest can be found at the Riviera Maya.
