To find cars in Chicago using Craigslist, go to Craigslist.com, and select Cars + Trucks under the For Sale category. Narrow the search by filtering according to make, model, year and location in the Chicago area.
From the Cars + Trucks category, you can select all cars and trucks for sale, those listed only by owners or those listed by dealers only. A text list of cars for sale is presented, sorted by newest listings at the top. Switch the list to thumbnail, gallery and map views by using the buttons at the top of the list. Narrow the list to the desired area of Chicago or cities near Chicago using the drop-down menu at the top.
Use the search box at the top of the list to narrow the search by entering information such as make, model, year and any other keywords you desire, such as "low miles" or "like new." Selecting a car retrieves the ad with the information about the car, and photos if posted. Respond to the ad by looking for a phone number in the ad or a Show Contact Info link. The reply button at the top of the ad always displays an email link, plus a phone number if the seller posted one.
