Which USENET Newsgroup Is Best for Learning about Buying and Selling New and Used Cars? I just picked this one out of the hat.

I do not want to be a "professional" or "licensed" broker, (because I've had all the licenses and certificates I'll ever need in one life
time, and I've had all kinds of licenses and permits for all kinds of occupations and services and as far as I'm concerned they ain't worth the toilet paper I'd use them in place of. The only thing that matters as a guerrilla broker is my negotiation skills. I want to sell myself as a professional negotiator to personally accompany a car buyer as my client, limit the session to 60 to 90 minutes per client, and get kicked out often enough to establish a reputation. After awhile I'll find the water level where me and my clients can do business. I will also limit the total commission to a maximum of $500 (often only $200).
Also can you tell me if there is a relatively reliable formula to determine when in fact the figures that I'm offering a dealer are up against the dealers 1st level of true real cost. I know there are other invoices that undermine whatever a dealer says are his "true" costs, so is there a rough formula to determine when the 2nd level of true cost has been met? Are there in fact more then two levels of real cost with corresponding invoices that I may or may not be able to check?
If you could use an example an MSRP of $29.5K, what would be the counter offer I would have to drop below to know there was no more room for negotiation for a level 1 cost and for a level 2 cost.
Assume I had only $2K down, only average credit (550-650), I'm asking for factory rebate if available (e.e.g $2400) plus 0% interest financing, all extended warranties bumper to bumper, and I'm dealing with a fleet manager or somebody other than a commissioned floor salesman so the commission factor is as low as possible.
Thank you.
