Looking For Datasets On US Automotive Advertising

Anyone know where I can find data on advertising by the automotive industry in the US? Right now I’m just trying to see what’s out there, so there’s some flexibility in the kind of data I use. Importantly, though, I need data that has information on advertising by region, which automakers are running the ad, and the language of the advertisement. It’s fine if I have to pay for it, but free is always nice.

Thanks.
