A binding estimate is a price commitment: the transport company agrees to move your vehicle for a stated amount, and that amount does not change unless you change the shipment. A non-binding estimate is a projection that can be revised before pickup. The distinction is the single biggest source of billing disputes in car shipping. Both types start the same way — you provide origin, destination, vehicle, dates, and service type. What differs is what the number means afterward. For a binding estimate to hold, the described shipment has to match reality. Things that legitimately change the price: None of those are gotchas. They are different shipments. An honest carrier states plainly what would change the price at the time it quotes.
Why brokers structurally struggle here: a broker does not own a truck, so it does not know its own cost until a carrier accepts the load on a load board. If no carrier takes it at the posted rate, the broker either raises the offer — and passes that to you — or the car sits. That is the mechanism behind most "the price went up" stories. Not always malice; often just a business model that prices before it knows its cost.
A carrier quoting its own truck knows its cost: fuel, driver, deck space, and the route. That is what makes a binding number possible. Auto transport has a bait-and-switch reputation and it was earned honestly. The pattern is familiar: a very low online quote, a deposit, silence, then a call three days before your flight saying no carrier will run it at that rate and the price is now several hundred dollars higher. At that point you have no leverage.
A binding estimate removes that dynamic. You know your delivered cost before you commit, and you can budget the rest of your move around it. Ask for it explicitly. Ask what is included — pickup, delivery, fuel, and any surcharges — and ask, in writing, what could change the number. A carrier that owns its equipment can answer both questions in a sentence. See auto transport companies to avoid for the rest of the warning signs.
Choosing the lowest quote. In this business the cheapest number is frequently the one least likely to be the price you actually pay, because it was generated to win the booking rather than to move the car. Compare quotes on three things instead: the total delivered price, whether it is binding, and who owns the truck. A binding number from a carrier that is $100 higher than a non-binding broker quote is almost always the cheaper shipment by the time the car is in your driveway in Naples.
The second mistake is not reading what voids the estimate. If you book a "sedan" and hand over a lifted F-250 with 35s, the price changes — and it should.
