Carwoo http://carwoo.com does something similar where the buyer submits what kind of car they're looking for, and local dealerships will submit bids, after which you can send them a counteroffer. The last time I used it was 2 years ago so wouldn't know if they've changed features since then.

Carwoo sounds interesting and it is similar to what I was thinking. But I think I might be imagining something more aggressive, where the startup sends an e-mail/fax/phone call to dealerships on the customers behalf. Acting as their "agent" almost. Also, it seems CarWoo only includes partnered dealerships. With the method I described a buyer would be able to contact every dealership of their interest. The only issue with this is that since the startup would be more "customer oriented" rather than dealer, it would probably have to charge customers (unlike Carwoo) instead of charging dealers like CarWoo.

I think I paid ~$60 for the service that they're offering for free now.
