I dont think it would be too hard to find parts for a honda civic, also its not 20 years old its 13.
However I agree that its time to part ways. My car is at 197,000 and im just waiting for the day it completely takes a s***. Im trying to get my credit in order and figure out exactly what I want before that happens. I say put the 2k down on either something new or something you like that is rougly used. With 2k down im sure you will get something, most likely with high interest but atleast you will have wheels.
