The full story
Why National GMC 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 thingDoc fee is genuinely reasonable
$0 is $457 below the UT average of $457. That's money you keep — most dealers in their market charge more.
! Where to push back
1 thingThe listing isn't quite the price
Quoted prices run about 6.3% above the advertised listing. On a $35,000 vehicle that's roughly $2,205 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.
