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

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 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.
4. 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.
