The full story
Why Vanguard GMC of Sherman earned this grade
Between May 2026 and October 2026, CarEdge negotiated or logged 16 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 thingShoppers who negotiated saved real money
Across 4 back-and-forth negotiations we tracked here, buyers saved an average of $4,224 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
3 thingsDoc fee exceeds the state cap
Their typical doc fee of $375 is above TX's legal cap of $225. 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 $225 or lower. It's not optional; it's the law.
Mandatory add-ons show up on most deals
50% of quotes include add-ons presented as non-negotiable. Across all recent quotes, add-ons average $810. Expect them to try to include something — paint protection, nitrogen-filled tires, VIN etching.
TipAsk which items are genuinely required and which are dealer-added. Anything not required by the manufacturer or the state is worth pushing on.
The listing isn't quite the price
Quoted prices run about 4.2% above the advertised listing. On a $35,000 vehicle that's roughly $1,470 in extra fees or markup.
TipGet an OTD quote in writing before you visit. Compare it to the listing — if there's a gap, ask them to account for every line.
