Financing through Toyota

[pandables]

Okay, so I am in a rough situation. When I bought my Yaris, I still owed about 2k on my previous car, so that got looped into my Yaris financing. Well, when I bought my car, I was listed as the co-buyer, the buyer was listed as my boyfriend. Yeah, I know, big mistake. However, it is registered and titled in my name. Basically, does anyone know how I go about refinancing my car so I am the buyer or what to do in this situation. I have never missed a payment, never late, and I usually overpay when I make a payment. However, I know my credit isnt as strong as his. I would like to keep my car or find someone else to take over the financing.. I just need advice on how to go about this.

Thanks!
Amanda
