About the CarEdge Dealer Transparency Index
Most dealer rankings come from Google star ratings and Yelp reviews — easy to game, impossible to verify. The CarEdge Dealer Transparency Index is different. We score every dealer using verified out-the-door quotes: real PDFs, emails, and screenshots from actual transactions.
Each dealer’s transparency score (out of 100) is weighted across four dimensions:
- Fee Transparency (30%) — Is the doc fee reasonable compared to the state average?
- Add-on Behavior (30%) — How often does the dealer bundle add-ons, and at what cost?
- Price Accuracy (30%) — Does the listing price match the actual OTD price?
- Data Quality (10%) — More verified quotes mean higher confidence in the grade.
Grades: A (90–100), B (80–89), C (70–79), D (60–69), F (below 60).

How to Use This Data When You Shop
- Get an OTD quote in writing before you visit. Any dealer can send a worksheet by email — if they won’t, that’s a red flag.
- Ask for a quote with zero add-ons. Everything in the F&I office is optional. Say “please remove all dealer add-ons” and see what the price does.
- Anchor to the OTD, not the listing. Dealers with a gap between advertised price and final OTD aren’t being straight with you. Don’t negotiate off the listing number.
- Compare three dealers minimum. Even within the same metro, doc fees, add-on policies, and listing accuracy vary widely. Use this ranking as your shortlist.
Rankings are generated from the CarEdge Dealer Transparency Index, a public methodology that scores dealers on verified out-the-door quotes — not Google star ratings or paid placements. CarEdge refreshes the rankings daily as new verified quotes come in.
