To unlock Benny's Original Motor Works garage in GTA Online, you need to complete a few simple steps related to the “Lowriders” expansion. This is a special location on the map where you can upgrade certain vehicles.

You won't get access to Benny's right away. You'll have to put in a little effort and complete some simple tasks to unlock the ability to customize cars in this garage.

Lamar Davis will call you. If you are actively participating in the session, he is more likely to call. But the call may not always go through. In this case, open the map and find the LD marker, which indicates a mission from the “Lowriders” series.



After completing the mission, the storyline with Lamar will open up.

Don't rush, it's not over yet. After completing the mission described above, you have to complete another one. This task is also marked with an LD icon on the map, but there will be a number 1 next to it.



You must go to this location and start the mission. You will see a cutscene of Lamar and Benny meeting.

After the cutscene of meeting the legendary car customization master, another mission will become available.



But you don't need to complete it, as Benny's garage will already be open. Just return to the open world and find the garage. From this point on, you can bring suitable cars there and customize them however you want.
