I think it is key to point out here that there are different audiences or markets in the car buying and selling world.
There are people here in this group which are (like me) grizzled older men (over 40) with mechanical experience, patience to shop around, cheap / frugal, and willing to put in some elbow grease to make something right.
Then there are people like a single soccer mom, young adult, or perhaps some one that grew up in a house without screwdrivers and hammers. My old neighbor for example. He had a handy man come hang ceiling fans for him because he knew nothing of the process and it was like magic that you could flip a switch and make a fan come on. Brilliant guy in his chosen field and high functioning, might have even been a genius, but throw him a crescent wrench and he wiggs out.
That second group is a growing section of our society. Carvana caters to them. They will pay a little more to feel like they are getting a no haggle (because they don't feel comfortable bargaining / negotiating) deal on a car that is basically a certified pre-owned vehicle that has had a full mechanical review and all new fluids. It comes with a bit of a warranty - even if it isn't a real warranty, it's a perceived value in their head that the car has had a full diagnosis.
I think if you were going to sell to this group on AZGO, you'd find a dealership called "Just Vehicles" where they sold cars with 100k+ miles on them, some blems, and a mechanic went through it and made a list but didn't fix any of it. They give you the list of things you need to fix when you buy the car. You get to negotiate heavily on the vehicle because everyone knows the sticker price is easily double what they are going to let it go for and it comes with a glove box full of your favorite ammo.
