Me and my girlfriend and our 3 month baby live in a 1bdrm paying $820 a month but we want to upgrade to a 2 bdrm in our apartment complex. When our lease is up she will be ten months. We have a 2000 Dodge Non an the a/c sucks for our baby sometimes she sweats...should we upgrade apartments and now pay $999 a month so she can have her own room and decorate it nice for her or should we finance for a better car?
