@Ken Rishel the example you gave is about an Auto Sales group. Link: http://www.jdsupra.com/legalnews/doj-settles-fair-lending-case-against-au-25772/
From what I can tell from the court case, they were NOT seller financing.
From the article: The amended complaint alleged that there was a “statistically significant” disparity between the dealer markups charged to Asian and non-Asian borrowers; many of the non-Asian borrowers were Hispanic. In addition, the DOJ alleged that the higher rates charged to non-Asian borrowers stemmed from Union Auto’s practice of giving its employees “discretion to engage in subjective decision-making and set overages within broad parameters.”
The article goes on to say: In March, the Consumer Financial Protection Bureau (CFPB) issued guidance on Indirect Auto Lending and Compliance with the Equal Credit Opportunity Act. The guidance targets dealer markups. The CFPB’s focus on indirect auto lenders is likely to generate increased referrals to the DOJ of alleged fair lending violations by both lenders and auto dealers.
It sounds like a scumbag car dealer got was coming to him/her. I don't see how this relates. If the auto dealer charged the same amount to Asians and non-Asians there would have been no discrimination.
