One of those other youtubers had a video of how Emilia and 2 others were given allocations from Chevy with priority builds
This kid had 1M+ subscribers.
Its cheap advertising for Chevy.
They buy the car and plaster multiple videos that get hundreds of thousands to millions of views.
All Chevy had to do was make sure the dealer didn't fuck them over when it came time for delivery.
Dodge loves mentioning youtube viewers in their press events. Same reason. Cheap advertising
