Hi there. I did a search for cars for sale by owner in the area and found a couple that look promising:
2007 Honda Civic EX with 113k miles for $5900:
2008 Mazda 3 with 102k miles for $5300:
In general, you want to look for cars that have a documented service history, no prior accidents, and friendly and honest private party sellers.
Make sure to arrange a mechanical inspection for any car you decide to pursue prior to making an offer. That way you know exactly what you’d be getting.
Let us know what other questions come up in your search.
