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

1. 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.
2. 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.
3. 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.
4. 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.
