new wheels...

I would really like a new car. Not necessarily brand new, just new to me. There is absolutely nothing wrong with my car. Its 3 years old, and with the exception of the tiny dent in the driver side door, in good shape and fine working order. It is also still being paid for. I have around 2 years left on my loan. I bought it brand new and its in my name. I was proud of this accomplishment. The only negative thing about my car is that it is a two door. I'm thinking that might start to get old having a baby in tow. A four door or small SUV would give us a little more room and be much better for traveling. I have a few cars in mind that I like, but to afford them and still live comfortably, it would have to be used. I'm not against used cars, but I really liked buying my car brand new and being the first one to own it. How do you think having a baby with a two door car would work? I'm just not sure...
