So what did Bob have to say about the campaigns? Let's let AdAge's Jean Halliday tell you:

Specifically, he told the brand teams last week that Cadillac's generally well-received and popular ads with "Grey's Anatomy" star Kate Walsh from Modernista are too dark and said Chevrolet's campaign from Campbell-Ewald — still in the can and yet to run — is too lifestyle-focused.

But it was Buick that took the most public beating for the uninspired "photo shoot" TV commercial that aired broadly for about a month until last week. In his public webcast, Mr. Lutz singled out that spot, saying, "That Buick commercial tested very well, which is not the same as saying that it's an effective ad." Buick VP Susan Docherty told Ad Age the pretesting landed in the "top quartile" for originality and breakthrough work.

So apparently Cadillac's ads are too dark (we disagree. Kate Walsh makes us want to buy a CTS), Chevy's ads (which haven't run yet) are too lifestyle-y, and Buick's ads (the beach photo shoot) are not the "lyrical gangster" but rather, just stupid. So what will this mean for GM's ads? More than likely, given Lutz's love of the old school, he'll be looking for more "beauty shots" (aka car p0rn) and less screwing around with non-car crap. Also, expect less pre-testing and a bit more of the classic "Mad Men" marketing. We're also expecting Publicis Group's Leo Burnett — responsible for the terrifyingly bad Buick ads — will more than likely continue to be taken to the woodshed until eventually taken behind for a good ol' fashioned Ol' Yeller recreation. Sad ad agency is sad.

And as far as Bob Lutz's little trip to the Caribbean, the man's like 80-something — who am I to argue with him wanting a little vacation time? [AdAge via Detroit News]

Kate Walsh
How do you top the smoky voice and unsubtle dialogue? The question is: when you turn on that famous Cadillac CTS ad, does it return the favor?

Brooke Shields
Renowned cougar Brooke Shields is, along with a talking Beetle, the voice of Volkswagen in America. She reminds women you can be sexy and still drive a Volkswagen minivan... if you look like Brooke Shields.

i-Miev Mom
Even the Japanese have gotten into the act, as evidenced by this commercial for the electric Mitsubishi i-Miev. Though maybe it's better to call her a spokesmilf?

Heidi Klum
Volkswagen has gone crazy for the German model-cum-host, using her in a variety of print and television ads, including some with her famously well-built husband Seal. Why does VW love the spokescougar so much?

Kim Cattrall
We're getting a bit sick of Kim Cattrall. Part of the fun of the spokescougar is the tease, but Cattrel pushes it too far. The proof? Her Nissan Tilda ad was pulled from New Zealand television for being too sexy.

Jill Wagner "The Mercury Girl"
Everyone's favorite spokeswoman Jill Wagner was, for a while, more famous than the Mercury brand itself. Having just turned 30 she's a bit young to be a true cougar, but she gets special consideration for being the spokesperson for the brand who invented the Cougars.

Susan Lucci
When Susan Lucci first stepped out to hawk the unsexy Ford Windstar she became one of the earliest modern spokescougars.
