How to promote with autoblogs?

I understand the concept of autoblogging and how it generates good SEO, but I still can't see how to turn it into actual cash. Let's say I want to target a niche market, lets say Performance Cars. I could then have an autoblog about Honda, a separate about Nissan, and a third about Toyota (of course I will have way more than this but this is for an example).

Now what types of articles do I post on the autoblogs? Just pull random articles about cars w\ some modifications to the article for SEO? For example, an article about Honda releasing it's new concept car would be posted on all my ABs since it is all relevant information to the tuner niche. If I find a good Toyota specific article I may mix it up a bit and post it just on the Toyota blog. Then I just have ads riding all around the blog hoping x percentage of my readers click the ad and buy?

Or rather do I post information on the products I am selling, kind of like a sales pitch?

Could anyone possibly show me an example of a good autoblog.

Thanks. I have been checking them out. Is the following a good model to use? eforextips(d0t))n3t? (damn filter lol)

This autoblog is offering Forex news and tips in blog form but also has a list of "featured products" and products I "recommend." Readers viewing my blog like my articles and also get a sense of confidence that I know what I'm talking about so they go check out the products that I recommend. Obviously I would apply this methodology to my niche but is my thinking on track?
