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 Hiley Auto Group in Arlington, TX, that has meant 7 verified OTD quotes from the past year across 2 negotiated deals logged into our database. Each one is a PDF, an email, or a screenshot showing the actual dealer fees, the actual add-ons, and the final price against the advertised price — not a salesperson's promise.
Only quotes from the past year count. We split them into four groups, newest first: the newest counts 50%, then 30%, 15% and 5%.
Fee Transparency
30%Are the dealer's fees reasonable? We add up every dealer fee and compare the total with the state median.
Add-on Behavior
30%How often does the dealer include quoted add-ons like paint protection or theft deterrent, the kind you can't say no to? Add-ons the dealer marks as optional don't count against them.
Price Accuracy

Data Quality
10%Does the quote list taxes, dealer fees, add-ons and government fees each on its own line? Each one is worth a quarter.
