Story:
After the discussion between Mike and Diaz, Casey came to see Diaz. Diaz has been informed about the dealership. It's a business empire actually. Mike and Lance shouldn't take it over because they've been seen there and they would be marked if they do. So, Casey and Milton decided to take it over. After taking it over, you can do reposession side-mission which I will publish soon in the future.
Note:
This mission has been updated with a soundtrack.
