The full story

Why Liberty Buick GMC earned this grade

Between July 2025 and July 2026, CarEdge negotiated or logged 6 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 thing

Advertised pricing is largely honest

On average, the quoted price is only 1.4% above the listing — small enough to be fees, not markup games.

! Where to push back

2 things

Doc fee is slightly padded

$786 is $8 above the NC average of $778. Not outrageous, but worth questioning.

TipAsk them to match the average. If they won't, factor it into your overall price — every dollar here is negotiable.

Add-ons are baked into almost every deal

100% of quotes include dealer add-ons, averaging $2,395. This is their business model — inflate the OTD, then hope you don't line-item it.

TipDemand an itemized quote before signing anything. Every add-on is optional — refuse them unless you actually want them.
