I'm gonna back off my dispute advice. I would wait a couple more weeks for any response on the GW, but then I'd send it again reworded with a copy of that letter. I would even go as far as to send 3-4 letters at the same time but include at least one to a higher-up at Honda Finance. Use dispute as a last advice.
This isn't stretching the truth, IMO, but I would see comments found in your myFICO reports and also TC, as you used and posted I believe, and include quotes from these reports in the body of your letter. Keep it very friendly and keep it short.
