Articles could be helpful.

Be sure you do your research to see what people search for, like "used cars in chicago" then target this. Put this in your meta description and use your keyword/phrase and like keywords/phrases throughout your site.

Hey yes the keyword is "used carz in CITY". Lets say i will use articles, where should i place them. Should it be in mywebsite/ blog ?
