The full story
Why Dillon GMC earned this grade
Between October 2026 and October 2026, CarEdge negotiated or logged 3 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.
✓ What they do well
1 thingThe price you see is the price you get
Their quoted selling price almost exactly matches the advertised listing price. No mystery markup, no surprise "market adjustment."
! Where to push back
2 thingsDoc fee is slightly padded
$549 is $153 above the ID average of $396. Not outrageous, but worth questioning.
TipFactor it into your overall price — every dollar here is negotiable.
Quoted add-ons show up on most deals
100% of quotes include add-ons that aren't marked optional. Across all recent quotes, add-ons average $1,795. Plan on seeing them on your quote.
TipAsk for an itemized quote before signing, and ask the dealer to confirm in writing which add-ons, if any, are required.

How we know this
Every number on this page came from a real deal.
Most dealer review sites scrape star ratings and count angry posts. We do the opposite. CarEdge shops for cars alongside thousands of real buyers every week — and when we negotiate on their behalf, we capture the full out-the-door breakdown the dealer sends back.
For Dillon GMC in Boise, ID, that has meant 3 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.
