The full story
Why Diamond Buick GMC earned this grade
Between November 2025 and November 2025, CarEdge negotiated or logged 1 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
1 thingDoc fee exceeds the state cap
Their typical doc fee of $350 is above MN's legal cap of $125. This is a red flag — every dealer in the state must stay at or below this number.
TipTell them you expect the doc fee at $125 or lower. It's not optional; it's the law.
