How we know this
Every number on this page came from a real deal.
Most dealer review sites scrape star ratings and count angry posts. We do the opposite. CarEdge shops for cars alongside thousands of real buyers every week — and when we negotiate on their behalf, we capture the full out-the-door breakdown the dealer sends back.
For Castle Hyundai Downers Grove in Downers Grove, IL, that has meant 23 verified OTD quotes across 1 negotiated deal logged into our database. Each one is a PDF, an email, or a screenshot showing the actual doc fee, the actual add-ons, and the actual final price — not a salesperson's promise.
Fee Transparency
30%Is the doc fee reasonable, or is it just profit? We compare it against the state average — and the legal cap, where one exists.
Add-on Behavior
30%How often does the dealer stick you with mandatory add-ons like paint protection or theft deterrent — the kind you can't say no to? Add-ons the dealer discloses as optional don't count against them.
Price Accuracy
30%Does the advertised listing price match what you'd actually sign for? We flag dealers whose out-the-door diverges from the listing.
Data Quality
10%More data = more trustworthy grade. Dealers with lots of recent, complete quotes score higher for consistency.
