The full story
Why Coulter Buick GMC Phoenix earned this grade
Between April 2026 and April 2026, 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 is slightly padded
$599 is $3 above the AZ average of $596. Not outrageous, but worth questioning.
TipAsk them to match the average. If they won't, factor it into your overall price — every dollar here is negotiable.
