The full story
Why Colonial Buick GMC earned this grade
Between October 2025 and July 2026, CarEdge negotiated or logged 5 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 thingsDoc fee is genuinely reasonable
$695 is $103 below the GA average of $798. That's money you keep — most dealers in their market charge more.
The 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."
! Where to push back
1 thingQuoted add-ons show up on many deals
60% of quotes include add-ons that aren't marked optional. Across all recent quotes, add-ons average $53. 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.

For Colonial Buick GMC in Loganville, GA, that has meant 5 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.

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
