webuyanycar.com USA and CarMax sell the same basic promise: get a number online, bring the car to a location, let someone look at it, and leave paid the same day. Both hold the offer for 7 days. The differences are in what the fine print says can happen to that number before you are paid, how the car gets to them, and how specific each one is about the payment itself. Everything below comes from each company's own sell page, verified for webuyanycar on 2026-10-27 and for CarMax on 2026-10-23.

Where they match: a week to decide, and money the day you hand over the keys
Neither buyer charges you to find out what the car is worth, and neither pays you before a person has seen it. webuyanycar gives a free instant valuation and offers a 7-day option on the number; CarMax gives a real offer in minutes that is valid for 7 days. Both then move the sale to an appointment where the car is inspected and you are paid the same day. That shared shape matters when you shop them against each other: you can collect both numbers in the same sitting, sit on them for a week, and only book the appointment with the one that came out ahead.
Payment: the one place webuyanycar is more specific
webuyanycar states the payment methods in full: at the appointment you choose a check, ACH, wire or Zelle, paid the same day. CarMax says you are paid on the spot but the sell page we verified does not name a method, so if you need the money a specific way, confirm it with the store before you drive over. If instant electronic payment is the deciding factor for you, webuyanycar is the one in this pair that puts Zelle and wire on the page, and AutoNation is the other buyer in our data that names an instant Zelle option.
The clause to read before you drive to the branch
Both offers are conditional, but the wording is not the same. CarMax ties the offer to the accuracy of what you entered and to in-person verification: 'Most qualify. Some we'll ask to verify in-person.' The number is for the car you described, and honest answers are what protect it. webuyanycar's language is broader. Valuations 'may be adjusted at our discretion at any time, including prior to or during our in-branch vehicle inspection', and the page adds that 'additional fees (e.g. titling) may also apply'. Read plainly, CarMax's offer can change if the car does not match your description, while webuyanycar reserves the right to adjust the valuation whether or not it matches, and may deduct fees on top. Neither page states the size of any adjustment or fee. The practical move with webuyanycar is to ask, before the appointment, what titling or other fees would come off the number and under what conditions the valuation would move.
Getting the car to them: 85 branches versus a store network plus pickup
webuyanycar runs 85 US branch locations and expects you to bring the car to one for the in-person inspection. Its alternative is a mobile buying service that brings the appointment to you, but availability varies by area, so whether that is on the table depends on where you live. CarMax works from its store network, with a state-by-state selector on the site, and the default is a store appointment. CarMax also offers home pickup, though not in all locations and with the note that 'distance restrictions and fee may apply'. Neither page states a price for its come-to-you option, so in both cases the only way to know what collection costs is to ask when you book. If driving the car in is the plan anyway, the practical question is simply which of the two has a location closer to you.
Which one to start with
- You want the payment method on the page before you go: webuyanycar, which names check, ACH, wire and Zelle, all same day.
- You want the offer tied only to your description being accurate: CarMax, whose contingency is accurate info and in-person verification rather than adjustment at the buyer's discretion.
- You want to start from a plate instead of typing the car's details: CarMax, which quotes by license plate or VIN.
- You want to hold a number while you decide: both give 7 days, and CarMax's Offer Watch covers the time beyond that.
- You want the car collected: both offer it with area caveats and neither states a price, so ask both for the cost first.
- You are booking with webuyanycar: ask about titling and other fees before the appointment, since the page says they may apply but does not state them.
