car buying blueeessss

We are currently looking for a newer car. I refuse to buy new cars because they are a waste of money, and I am pretty close to refusing to buy a used car because they are also a waste of money. I still drive the car I drove in high school, it is currently 10 years old and has never given me a days trouble. We have an explorer that doesn't move unless we are going home and the dog is with us and then we have Jason's baby, the CRX. I don't want to spend the money to get a car, is that bad? Ours are fine, sure it would be great to have a four door car especially since the baby is on the way but I don't think it is a necessity. I know four doors make things much easier but if I am used to loading the baby in a two door I will never know the difference. My sister bought a new vehicle a few months ago and her payment is outrageous! We aren't poor or anything but geez, I do not want to be stuck with a big payment on top of childcare. I enjoy not having a lot of debt (aside from my house). I also do not like to part with things that I have had for awhile. I will probably cry when we sale the truck lol.
