The teaser would be better if it showed you getting a warning for posting the 1,000th image of that same friggin car.
I recreated the screenshot, the GM looks a lot crispier (the taxi varient, though the livery may look crispier due to the contrast affect on the screenshot menu, theres also a new chrome and black grille for taxi version which to my knowledge is new and theres a new avertisment on the roof being the Sharpie ad instead of the Turboburger one). The normal GM still looks the same, I couldn't get the angle 100% correct but its mostly there. I left in the 800-series and LeGran for orientation.
ok so maybe there's is a few differences nothing in the shape of the car tho but we can notice how the teaser livery is slightly orange-ish compared to the current game state I also notice that the bumper blinker looks slightly better quality on the teaser
