You find the car online. The price works. You drive to the store, take the test drive, sit down to sign, and the paperwork carries a line the listing never showed you: a documentation fee, several hundred dollars, non-negotiable, presented as if it had been there all along. Sometimes it was there, buried in fine print. Sometimes the dealer's own specials page describes it differently than its vehicle pages do. Sometimes the advertised price quietly excludes it. The doc fee is where the surprise lives in a car deal, so that is where CarThrive grades dealers. This page explains exactly how the grading works, what evidence it rests on, and what it does not claim.
Every CarThrive Price Transparency Grade answers five questions about a dealer's published pricing. Nothing else is scored: not the sales staff, not the service department, not the coffee. The questions, and their weights:
30 points
The published doc or admin fee, scored against the regional market. In our Massachusetts and New Hampshire sample of dealers who publish a dollar figure, fees run from $196 to $899, with a median of $597. A smaller fee earns more points on a fixed scale, shown in the table below.
30 points
The question shoppers actually feel, and the standard Massachusetts law and the FTC both describe. Full marks when the fee appears as an itemized line inside the displayed price. Partial credit when it is folded into an all-in price but never broken out (18), when it appears in vehicle price stacks but goes missing from specials or another channel (15), or when the dealer discloses the fee but deliberately keeps it out of the advertised price (6).
20 points
Disclosure. A dedicated public fee page earns 20. The amount printed in the price stacks on vehicle pages earns 16. An amount that appears only in disclaimers and fine print earns 12. No public amount at all earns 0, and a dealer with no published figure cannot be graded until one exists.
10 points
Consistency. One fee figure, presented the same way everywhere we check, earns 10. Points come off when a second disclaimer template or a different channel contradicts the main presentation, and the score drops to near zero when the site states two different dollar amounts for the same fee.
10 points
Checked on vehicle pages. No forced add-on in the checked presentation earns 10. A mandatory add-on product baked into every price, or a required package excluded from the online price, drops the score to 2. Optional extras a buyer can decline do not count against a dealer.
The fee level scale, against the regional sample:
| Published doc or admin fee | Points of 30 |
|---|---|
| $300 or less | 30 |
| $301 to $450 | 26 |
| $451 to $549 | 22 |
| $550 to $649 | 15 |
| $650 to $749 | 9 |
| $750 to $849 | 5 |
| $850 or more | 2 |
The five scores add to a total out of 100, and the total sets the letter:
| Grade | Total score |
|---|---|
| A | 88 to 100 |
| B | 75 to 87 |
| C | 60 to 74 |
| D | 45 to 59 |
| F | Under 45 |
One rule protects shoppers from half-finished homework: a dealer whose fee is verified but whose price presentation has not been checked yet gets a provisional fee score out of 60 (fee level, disclosure, and consistency only) and no letter grade. Letters are earned on the full check or not at all.
Every grade is scored from what the dealer publishes: the price stacks on its vehicle pages, the terms on its specials pages, and its disclaimers. No secret shoppers, no purchased data, no estimates. If a fee amount does not appear in the dealer's own public text, the dealer is listed as ungradeable rather than guessed at. Each grade carries the date it was checked, and grades are re-scored when a dealer's pages change. Two checks from October 2026 show what that means in practice:
What a grade is not. A CarThrive Price Transparency Grade is not a review score and not a judgment of the whole dealership. It says nothing about whether a store treats people well, services cars competently, or offers a fair deal on any particular vehicle. It measures one thing: how transparently the dealer publishes its fees and prices, judged from the dealer's own pages on the date checked.
CarThrive is not the only scorekeeper. CarEdge, a national buying service, publishes dealer transparency grades built from verified out-the-door quotes, the prices its customers actually paid on completed deals. Its scoring weighs fee transparency, add-on behavior, price accuracy, and the quality of its data. That is transaction evidence: what happened at the desk, after negotiation, for buyers who used the service.
CarThrive grades the other end of the timeline. Our evidence is published pricing, the numbers any shopper can open and check from home before visiting a store, before any negotiation, whether or not they ever buy. The two methods look at different moments and rest on different records, so they are complements, not rivals. When both methods point the same way, as they currently do with Quirk stores graded at the top by both, a shopper has two independent reasons to be confident. When they disagree, that gap is itself worth knowing about.
Nothing in the rubric requires a dealer to be the cheapest in the market. The mechanics are plain:
Dealers are re-checked when their pages change, and a dealer that fixes its presentation can ask for a recheck. The grade follows the published evidence, in both directions.
A disclosure about us. CarThrive's publisher works in automotive retail marketing, including for a dealer group whose stores are graded here. The defense against that conflict is the record itself: Quirk stores currently hold two A grades and a D under this rubric, including a D for a Quirk commercial truck platform that published no fee line in its pricing at all, scored on the same evidence and the same scale as every competitor.
