Wasn't the German car thing this time. Already knew it was bad, it said "525i" on the back.
What I guess I have to explain is that basically this dealership is so desperate that he's offering to sell to you without any documentation - no proof of identity or solvency is required to purchase or finance a car from him, evidently. Basically, he's marketing to illegal aliens who are off the books.
Where the fail comes in:
1. The sign is in English, a language most illegals in this area (statistically) will have problems with. I saw the other side of the car, too - also in English. No note of Hablo Espanol, either.
2. All of his major competitors run targeted ads (in Spanish) on public transport, public billboards, or simply with fliers at gatherings. Most of the little guys as well. Because that's where people with no cars are going to be. I've not seen any dealer advertise with remarkably tacky magnetic signs on the side of their car in recent memory.
3. It's on a car that's going to get his target market profiled and stopped in a hurry by some police departments, and his target market knows it. So they won't want it.
If he had run the sign in English and Spanish on the side of an SUV, pickup truck or economy car, it might be a good idea. This? This is desperation and fail.
