The full story
Why Thompson Buick GMC earned this grade
Between December 2025 and July 2026, CarEdge negotiated or logged 3 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.
! Where to push back
3 thingsDoc fee exceeds the state cap
Their typical doc fee of $899 is above MO's legal cap of $621. 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 $621 or lower. It's not optional; it's the law.
Add-ons are baked into almost every deal
67% of quotes include add-ons the buyer couldn't remove, averaging $3,234. This is their business model — inflate the OTD, then hope you don't line-item it.
TipDemand an itemized quote before signing anything, and ask them to justify every "required" charge in writing.
The listing isn't quite the price
Quoted prices run about 3.4% above the advertised listing. On a $35,000 vehicle that's roughly $1,190 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.
