Cadillac to GM: Should I Know You?

As parents of the 1970s will attest, once the Led Zeppelin albums start playing, it's only a matter of time before the kids are embarrassed to be seen with you.

Business Week reports that Cadillac is afraid General Motors' bankruptcy brands it with a stigma that will hold it back from connecting with the high-end customers it seeks, so the GM logo, Red Tag sales and all other GM reminders are vanishing from Cadillac offices and dealerships...right down to a switch of e-mail addresses from @gm.com to @cadillac.com.

And somehow, GM's going along with this...which means exactly what, I don't know.
