Three options as I see it;
Try one or two other banks if your dead set on financing for 12 months.
Or go back to your bank and finance it for 48 months and on the 12th month - pay it off outright. Just make sure you have that option in your financing without penalty, which most banks do. Pretty standard stuff.
Then a month later you can write a f&*k you letter to your bank
Or, just pay cash for it
