I have seen some people asking before in this forum which bureau NMAC (Nissan Motor Acceptance Corp) pulls when purchasing a vehicle. I came across a sheet that gives that information. Figured I'd post the info for reference. Marv, you can make this a sticky if you wish.

In states where your EQ is served by CSC, the will pull EQ/CSC. Of course, this list doesn't mean that competent F&I personnel couldn't request they pull another bureau. It's all about relationships, IMO.
