Another option for consumers looking for cars for sale by owner is to look in local newspapers. The Chicago Tribune has a separate part of its classified section dedicated to the automotive industry. While there are often listings from dealerships, private sellers can also place ads in the paper. The Chicago Tribune also has an online automotive search option powered by Cars.com, notes its official website.
