I could see it working in some cases and then completely failing on others.
Considering meme culture is mostly tailored to younger adults and teens (24 and under), I can't imagine many sales would come from this as they aren't really the greatest demographic to target for vehicle sales.
But on the other hand, if a teenager's parents are getting ready to buy the teen their first car and the teen sees this ad on social media they might be inclined to recommend their parents go to that dealership when they are shopping around.
