Car commercials in general suck. Especially local car commercials.
In my city there's two guys who are complete sleaze balls in their commercials (and supposedly in real life too). One of them has his ads play at least twice, sometimes 3 times during commercial breaks. The other uses his wife and daughter to do the ad for him, both of them have that fake smile that car dealers use in their ads and both talk in the most uninspiring robotic voice I've ever heard from a seller of any kind.
As bad as they are though, neither of them are as bad as the one who made his kid portray himself as "The most interesting kid in the world" a la those Dos Equis commercials. It was so bad the dealership either went out of business or someone else bought it because I haven't his ads in about 5 years.
