I think "everyone" in this scenario are car dealers. They created large barriers to entry for the rest of us, but obviously there's a market for it -- there are approximately 17.5k licensed franchise car dealerships in the US (quora link citing a National Automobile Dealers Association report), and lord knows how many car dealers with just the dealer license. I think the business angle that I would take, if I were to pursue this, is to use my car dealer connection strongly. He shops around for anywhere from a few to 20 clients a week, looking out for cars for them, mostly luxury vehicles. For him to find an undervalued car might not be worth the trouble for him to pick up, store somewhere, and look for and vet potential buyers. It's just not worth it to him. But my $600 is. I don't think I would do any repairs or investing into the car beyond a car stereo or changing a flat tire.If it was easy to do why isn't everyone doing it?
