The full story
Why Diehl Kia of Massillon earned this grade
Between December 2025 and May 2026, CarEdge negotiated or logged 6 verified deals with this dealership. We pulled the doc fee, the add-ons, and the gap between advertised and out-the-door price from each one. Then we graded them the way a friend in the business would: on the things that actually cost you money.
! Where to push back
1 thingThey never put a doc fee in writing
Across 6 verified quotes we could not confirm a single documentation fee. Almost every dealer charges one, and the OH average is $394, so a blank here usually means the number was left off the quote rather than left off the deal. An undisclosed fee is a fee you find out about at signing, and it costs this dealer the entire fee portion of their score.
TipAsk for the doc fee as a dollar figure in writing before you go in, and make sure it appears on the out-the-door quote. If nobody will name it, treat that as the answer.

For Diehl Kia of Massillon in Massillon, OH, that has meant 6 verified OTD quotes across 1 negotiated deals logged into our database. Each one is a PDF, an email, or a screenshot showing the actual doc fee, the actual add-ons, and the actual final price — not a salesperson's promise.
Fee Transparency
30%Is the doc fee reasonable, or is it just profit? We compare it against the state average — and the legal cap, where one exists.
Add-on Behavior
30%How often does the dealer stick you with mandatory add-ons like paint protection or theft deterrent — the kind you can't say no to? Add-ons the dealer discloses as optional don't count against them.
Price Accuracy
30%Does the advertised listing price match what you'd actually sign for? We flag dealers whose out-the-door diverges from the listing.
Data Quality
10%More data = more trustworthy grade. Dealers with lots of recent, complete quotes score higher for consistency.
