The full story

Why Sewell Buick GMC earned this grade

Between August 2025 and December 2025, CarEdge negotiated or logged 4 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 in line with the market

At $225, their doc fee sits at or just under the TX average. Not exceptional, but nothing to fight over.

Add-ons are the exception, not the rule

Only 25% of quotes include dealer-installed add-ons, averaging $999 when present. Most shoppers here never see them.

Advertised pricing is largely honest

On average, the quoted price is only 1.1% above the listing — small enough to be fees, not markup games.

! Where to push back:Nothing glaring. That's part of why they scored where they did.

For Sewell Buick GMC in Dallas, TX, that has meant 4 verified OTD quotes 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.
