There is nothing wrong with purchasing a vehicle online with nothing but pictures to go off of. There are some risks inherently involved in this process but its not a bad way to go. This guy is an idiot for trying to order a "super car" for an extremely low price, from some random (non-reputable) dealer (that was based in China nonetheless), and having no understanding of the process by they were supposed to be taking part in. He was acting fuckn stupid and paid the price for it. Congrats on your car purchases and sales. I hope they continue to go well for you.
