The full story
Why Mike Maroone GMC earned this grade
Between February 2026 and April 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.
✓ 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
$795 is $144 above the CO average of $651. Not outrageous, but worth questioning.
TipFactor it into your overall price — every dollar here is negotiable.
Quoted add-ons show up on many deals
33% of quotes include add-ons that aren't marked optional. Across all recent quotes, add-ons average $499. Expect to see items like paint protection, nitrogen-filled tires, or VIN etching on your quote.
TipAsk which items are genuinely required and which are dealer-added. Anything not required by the manufacturer or the state is worth pushing on.

For Mike Maroone GMC in Boulder, CO, that has meant 6 verified OTD quotes across 2 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.
