The full story
Why Mataga GMC earned this grade
Between October 2025 and October 2026, CarEdge negotiated or logged 10 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
2 thingsThe 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."
Shoppers who negotiated saved real money
Across 3 back-and-forth negotiations we tracked here, buyers saved an average of $2,440 from first quote to final. That tells you their opening number has room.
TipNever take the first quote. Their floor is lower than what they offer on day one.
! Where to push back
2 thingsDoc fee exceeds the state cap
Their typical doc fee of $122 is above CA's legal cap of $85. 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 $85 or lower. It's not optional; it's the law.
Quoted add-ons show up on many deals
40% of quotes include add-ons that aren't marked optional. Across all recent quotes, add-ons average $807. 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.

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 Mataga GMC in Stockton, CA, that has meant 10 verified OTD quotes across 3 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.
