The all new Buick Regal is coming to dealership lots - and the ad campaign "Moment of Truth" is stirring up a response.

It's part of a huge social media campaign for Buick, started by owner General Motors. It includes a new website, accounts on Twitter / FaceBook and other such websites. It also features very luxurious parties in cities such as Miami, Philadelphia and New York.

But what is Buick's "Moment of Truth" all about? The campaign gives party attendees FlipHD cameras to record their impressions, both positive and negative, of the new Regal. The videos will then be posted to a site for all online to see.

According to advertising specialists at Brand Week, these "Regal Remix" parties are "designed to help people become aware of exactly what the Buick brand means in post bankruptcy trim, and the shindigs dovetail with an aggressive internet marketing campaign targeted to 35-40 year-olds."

Buick hopes to bring in a fresh, young group of car buyers with smaller models like Regal, and the luxury car audience with GM's interior upgrades and extra features.

Buick's new campaign should kick off later this month with the launch of the Moment of Truth site.
