CarEdge, the AI-powered car buying platform, today launched the Dealer Transparency Index (DTI), the first public database that scores and grades U.S. car dealerships based on verified pricing data from real transactions. The DTI identifies the 10 best car dealers in Arizona. The Index is free at www.caredge.com/dealer-ratings.

Unlike review-based rating systems, every score in the DTI originates from CarEdge’s AI negotiation agent — the same technology that contacts dealers on behalf of real consumers, requests itemized out-the-door pricing, and closes deals. That agent has sent 440,000+ messages across 47,500+ dealer outreach sessions, saving buyers $19.6 million and counting — generating the largest verified pricing dataset in American auto retail. The byproduct: a 0-to-100 transparency score and A-through-F letter grade for every dealer in the system, calculated from actual doc fees charged, add-ons applied, and the gap between advertised price and final contract.

An Industry in Crisis
The 2026 CDK Friction Points Study reveals that the buyer Net Promoter Score for car dealerships has collapsed from +48 to +29 in a single year. Among online-only shoppers, the score has dropped to zero — signaling a total breakdown in digital trust. The FTC has finalized enforcement orders against major dealer groups for “payment packing” and charging for undisclosed add-ons. And 20% of buyers now defect to a different dealer when the initial advertised price fails to match the final showroom offer.
Yet the platforms consumers rely on to compare dealers — CarGurus, Autotrader, Cars.com — continue to award “Great Deal” badges based on listing prices that dealers routinely do not honor.
