Don't sell your vehicle to Carmax, they don't disclose their buying rules, until you sign over your
pink slip to them. I recently sold my vehicle to them and much to my surprise, they made me wait over three weeks to be paid for my vehicle that they had possession of.
Imagine a company as large as that holding on to funds and giving you a check that is no good for three weeks. They have your vehicle.Under no circumstances should you have to wait that long, to receive your money. When they make you sign a statement that the check must go into your account and when you deposit it they have a special routing number that instructs your bank to only make a portion of the funds available, then three weeks later, the rest of the funds available.
I didn't know that you sell your car and then must wait for your money in dribbles.....How professional is that.......
