Three Doors, One Question: Speed or Money?
Every "sell my car" search shows the same three doors: CarMax, Carvana, or doing it yourself. They're all legitimate. They pay very differently. Here's the honest comparison nobody in that search results page — all of whom profit from door one and two — will give you.
How Instant Offers Actually Work
CarMax and Carvana are retailers. They buy your car at wholesale-ish, recondition it, and resell it at retail. The gap between what they pay you and what they'll list it for is their business model — reconditioning, transport, lot costs, profit. Nothing shady about it. But that gap is the money a private buyer would have paid you.
CarMax: The In-Person Instant Offer
Online estimate, in-store confirmation, check on the spot, offer typically valid 7 days. Strong on straightforward, popular vehicles; the 7-day window makes it an excellent price floor
Carvana: The Driveway Instant Offer
Fully online, they come get the car, payment lands within days. The most frictionless selling experience that exists. You pay for that friction removal in the spread.
Selling Privately: The Money Door
More effort — photos, listings, calls, meets, paperwork — and consistently more money, often by four figures on desirable vehicles. The modern private sale is also less work than its reputation: a good listing plus a window sign with a $5 talking QR code lets the car pitch itself while parked, answer buyer questions out loud, and hand over a tap-to-text button — so the "strangers calling at dinner" era is mostly over. The full playbook is in how to sell your car privately.
The 2026 Play: Use All Three
- Get CarMax and Carvana offers the same morning (free, ~15 minutes total).
- The higher offer is your floor — you now cannot do worse.
- List privately at retail-comp pricing for the length of the offer window.
- If the private sale beats the floor, you win the spread. If not, take the instant offer before it expires. Zero risk either way.
Bottom Line
Need it gone this week: instant offer, take the higher of the two. Want the most money: private sale with the instant offer as your safety net. The only wrong move is accepting the first number without collecting the other two.
