I would have the links as prominent and important as possible. Also, you might consider doing them as a chain, so each has one way links. e.g. a-b-c-a ...
If it's affordable, hiring content developers (with a track history) is ideal, because you won't be able to generate content regularly for several sites.
It's a question of budgets and planning, where I'm concerned. Figuring out what you're going to outsource, what you do yourself, and how you monetize. Especially, it's important to know how soon you expect to make back your investment.
I'd use different domains, registered to different people/companies if possible. Depending on whether there's a geographic strategy or not (i.e. are you targeting a city, e.g. "NY used cars"), you might also want to consider having various hosting companies across the country. If there is a geographic strategy, get a few different hosts in your target city.
But then, these are just my humble opinions, based mostly on what i've read on SEO. My "network" isn't so succesful (though it is new).
