Using microformatting for multiple online review source

[autoczar]

I sat in on the Microformats & Schema.org – Real life Use Cases webcast today. Thank you for providing that helpful information.

This discussion question is related to microformat in relation to online reviews:

I work for a local auto dealership group. Each of our dozen+ dealers have reviews on Google, dealerrater, cars.com, edmunds, etc.

Is there a SEO benefit to compiling online reviews from multiple sources mentioned above into our site in a microformat (knowing the reviews existed elsewhere) or would we have to use a third party tool such as Bazaarvoice & capture our reviews through there?

Have any of you pulled reviews from various sources onto your site & used the microformatting technique? If so, what was the outcome?

Thanks
