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.
Only quotes from the past year count. We split them into four groups, newest first: the newest counts 50%, then 30%, 15% and 5%.
Each dealer’s transparency score (out of 100) is weighted across four dimensions:
- 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 (30%) — Does the advertised price include every charge you have to pay? We check each quote against the vehicle page: dealer fees, add-ons, the advertised price and the discount.
- 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.
Grades: A (90–100), B (80–89), C (70–79), D (60–69), F (below 60). Read the methodology →

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 advertised price. Dealers with a gap between advertised price and final OTD aren’t being straight with you. Don’t negotiate off the advertised number.
- Compare three dealers minimum. Even within the same metro, dealer fees, quoted add-ons and advertised price 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.
