I answered on behalf of the dealership that I worked for almost a year ago because I know they're still working with an in house BDC.
We did have an awesome business plan that we executed back in 2007 that enabled us to become an outsourced BDC and at one point we did BDC services for about 20 dealers all over the US. We had an automated dialer system that had us working leads for many Suzuki, Toyota, and Buy Here Pay Here dealers. It worked out very well, and Cathy Nuccio, the founder of Car-Appoint was brilliant. Unfortunately, when the market crashed, so did our business opportunity and it was soon history.
I would love nothing more than to see her embark on another journey in that direction. It was really a lucrative business and I learned a lot.
