I'd let them know you anticipate buying & financing many more cars in your life, as well as your family, friends, and co-workers... and that you have heavy influence, because as a member of myFICO.com, you have a vast knowledge of how credit reporting works, how to do personal credit repair, and everyone you know comes to you for credit advice, whether it's choosing which credit card companies to apply with, mortgage advice, or financing a car. And that if they were to change the reporting to more favorable reporting, you would be more apt to recommend financing vehicles with their company. I've used this tactic, and followed through on my word with referrals, when dealing with various vendors in my life and more than 50% of the time it has worked. So you offer them something, no threats as you never know what they are going to write down in your personal file... and you never know if you'll need to finance another vehicle with them again.
