The Illinois car dealer database,ranked before it is worked
1,099 Illinois dealership rooftops with employee counts, decision-maker counts and live inventory on every record, so a Midwest patch can be tiered into named coverage before anyone books a drive. 1 credit a rooftop, nothing to filter or preview.
What is the Illinois car dealer database?
The Illinois car dealer database is a rooftop file for 1,099 dealerships, and it is the one people reach for when the job is coverage planning rather than list buying. Three numeric columns do most of that work: total_employee_count, decision_maker_count and live inventory. Together they say how big a store is and roughly how many people a rep has to convince inside it - as counts, since there are no names in this product. Chevrolet leads the state's franchise mix. Illinois is also the clean case for a two-tier plan, because Chicago and the collar counties hold metro density while downstate runs as a string of smaller markets down to the Missouri and Kentucky borders, and city and ZIP filters split the state along exactly that line.
Tier the state before you assign it
Employee count and decision-maker count are on every rooftop, with range filters over both. Cut the top decile into named accounts, leave the long tail to inside sales, and you have a coverage plan built on the store's real size rather than on a rep's memory of it.
Chicago is not Illinois
The city, the collar counties and downstate markets like Rockford, Peoria, Springfield and Champaign carry different store densities and different drive times. Filter by city or ZIP to price each patch separately instead of averaging a state that does not average well.
Service and parts are their own budget
NADA counts franchised dealerships writing more than 276 million repair orders on over $1.3 trillion in total sales. Fixed operations is a spend center of its own, and each Illinois record carries the service and parts lines directly, so an offer aimed at that side of the store does not have to start at the sales desk.
Four columns free, twenty-four on purchase
Dealer name, Hermes dealer ID, OEM franchise mix and live inventory count are readable while you plan. The other 24 columns - address, phone lines, legal entity, tenure, headcounts, socials and website tech - unlock when you spend the credit, at 1 per rooftop.

Compliance & sourcing
Two things worth stating for a planning use case. First, freshness: the dealership export behind this page is rebuilt daily and the portal reads the current snapshot, so headcounts, inventory and technographics move with the market instead of sitting frozen from an old crawl - and records you have already bought stay yours when a detail changes. Second, remedy: if a record is wrong, the credit-back remedy in our terms is your remedy, and the data is licensed for use inside your business rather than for resale or redistribution. There are no individuals in the file, so no consent or suppression obligation attaches to the rooftops themselves.

Frequently asked questions
How many Illinois dealership rooftops are covered?
1,099, from the Chicago metro and the collar counties through Rockford, Peoria, Springfield, Bloomington-Normal, Champaign and the Metro East. Chevrolet heads the Illinois franchise mix. Franchised and independent stores sit in the same table on the same 28 columns.
Can I rank Illinois dealerships by size?
Yes. Every rooftop carries total employee count, decision-maker count and a live inventory count, and each has a minimum and maximum filter. That is enough to sort a state into tiers - flagship stores, mid-size points and small lots - and to hold the tiering steady, since the underlying export is rebuilt daily.
Does the Illinois data name the people at each dealership?
No. Dealers is firmographic data about the rooftop, and decision_maker_count is an integer, not a roster - there are no names, titles, emails or direct dials in the product. The named decision-makers at those same Illinois stores are in the Contacts product, which holds 10,964 verified Illinois dealership contacts at 1 credit each.
What does Illinois dealership data cost?
1 credit per rooftop record. Filtering, previewing and counting are free, so an entire coverage plan can be built and sized before any credit is spent. Credits come from one balance shared across contacts, rooftops and dealer groups, roll over month to month and never expire.
