I agree with the rest. Save and save as much as you can. The car wont last forever, other bills will start kicking in, and there will be extra expenses. I would save as much as possible and then some. More you save now with no bills the less you will pay later.
What I mean on this is in terms of interest on payments. Less interest more money in your pocket. What you do now will effect the rest of your life. Save and save every penny you can.
