Welcome to Millennium Auto Sales, home of the best used cars in Chicago, Illinois. We have worked hard to build a reputation for selling high quality used cars backed by extraordinary service. Most of our business is done with individuals who've never even driven the vehicle or seen it in person prior to purchasing. Only two things make that possible: unequaled quality and a high level of service. We offer a variety of car financing programs to meet the individual needs of our customers, and provide our customers with a variety of extended warranty plans to protect their used car after a purchase has been made. Please use the menu above to browse our current inventory and learn more about us. If you have any questions please feel free to call us at 773-286-0400.
