Work Tag line please help!!?

I work at a credit union and we are having an internal tagline contest. We currently have a promotion for automobile, motorcycle, and RVs with a great interest rate and we are having a contest as to who can come up with a great tag line. Something to grab the customer's attention and ask questions. I have a few ideas, but do you have any suggestions and/or ideas of a tagline. Please help a girl out.
