SAND LAND

In order to unlock the Vehicle Hobbyist trophy, you need to own seven different vehicle types. This means, obviously progressing the story, which has you picking up many different types. You will likely unlock this trophy by the time you reach Forest Land or soon after, and you will have access to the Hopper and various other extra vehicles. (You can switch out which vehicles you have on you by going to a garage and clicking on the Select Vehicle option; then you can slot the desired vehicle into your radial menu, accessed by pressing .) Once you have your seventh vehicle, the Vehicle Hobbyist trophy will unlock.
