Cook County — encompassing Chicago and 130+ surrounding municipalities — is the third-largest county by population in the United States and home to the Midwest's dominant private vehicle market. Chicago's extraordinary economic diversity (finance at the CBOE and CME, logistics at O'Hare, healthcare at Northwestern and Rush, manufacturing on the South Side) creates demand across every price tier simultaneously. Vehicle title and registration in Illinois are processed through the Illinois Secretary of State's offices; the Cook County Clerk's office (cookcountyclerkil.gov) handles county-level services. Illinois SOS facilities in Chicago are at 69 W. Washington Street and multiple suburban locations throughout the county. Illinois requires the seller to complete the title assignment and sign a Bill of Sale. The buyer must title and register within 30 days of purchase. Cook County imposes no additional vehicle registration fee beyond the state; however, the City of Chicago levies its own City Vehicle Sticker requirement ($90.88–$144.41 annually) that often surprises buyers relocating from suburban Cook. Chicago's lakefront — 18 miles of Lake Michigan shoreline — supports a high-density marina network at Belmont, Diversey, DuSable, and Monroe harbors. Private-sale sailboats, motorboats, and personal watercraft move actively through Chicago's marina community, particularly from April through October. Mobile notary services in Cook County average $35–$70. Illinois statutory notary fees are $1 per signature (5 ILCS 312/3-104); mobile travel adds $25–$50.
