If you scraped a bit, and did your best to save, how long would it take to save the 8k needed? It's probably going to be tough getting financing on a 10 year old 100k mile vehicle because the banks see them as high risk. (For good reason; what if you were in the same position 2 years down the road, only you had 2-3 years left on a loan for a car that would cost the rest of the loan just to get back on the road?)
You may be better shooting for something around 10-15k with low mileage and younger.
Congrats on the new baby by the way!
