A KIA? Might as well put a can on the back and a sticker on the side and join the ricer wanna be family.
I just have a thing against them, nothin personal.
Seriously though, It is up to you. I know I have the need for a fast sleek car but I also want to become debt free. I have no where near the 25g that you have but I haven't taken out school loans either. What you need to do is weigh in the facts. How wuch does it mean for you to have two cars, that you love to drive, and like the styling to then move to a car (KIA or not) that may not have all the features and all the power or all the luxury of what you have now. Not saying you will neccissarily downgrade from what you have now but how would you feel about it down the road.
My dad got rid of a car once because he never really drove it much anymore, he had a family now, a new house and so forth. About two years after selling it he really started to miss it. It was his first new car, a 1970 Torino GT. To this day he still kicks himself for selling it. Would you feel this way about either of your cars?
Like I said, I may be a little biased for Bonnevilles and against KIAs but just make sure that whatever you pick will be what you really want and need. Who knows, maye 5 years from now you will be out of debt and have just picked up your new 2008 V8 RWD Bonneville SSEi!
