Just look at it as a few more car payments. Plus, going forward, if/when you have a component that may need replacing, you've got the option of improving the car in the process. With my last one, for example, the front brakes were a little warped and needed new pads, and I spent a few extra bucks to put SVT rotors and braided stainless hoses up front. The difference in stopping distance and feel was noticeable and FUN.
