As far as I know the information is accurate. You and I are talking about the same ad, I believe: fast-paced, lyrics about "things you do to me," and ends with a reference to edmunds.com. I exchanged three letters with Chevrolet, and the responses were not form letters.
I read an article sometime in the past week (Time, Rolling Stone, on the Web...? Can't recall where) about the use of music in advertising. To use a rock song, advertisers may have to pay well over $100,000. A growing practice is to have your own music made by studio musicians. You own it, and it costs more like $10,000, and you can use it as many times as you want. I wish I could recall where I saw that. I think we have an example of that phenomenon here in the Chevie ad.
