The full story

Why Mataga Buick GMC earned this grade

Between April 2026 and May 2026, CarEdge negotiated or logged 8 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

3 things

Doc fee is genuinely reasonable

$0 is $104 below the CA average of $104. That's money you keep — most dealers in their market charge more.

Add-ons are the exception, not the rule

Only 25% of quotes include dealer-installed add-ons, averaging $1,835 when present. Most shoppers here never see them.

The 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:Nothing glaring. That's part of why they scored where they did.
