If you thought that $5000 model Nissan GT-R was expensive, wait until you read up on this 1/18th scale model Lamborghini Aventador LP 700-4 that is reportedly expected to sell for $4.2 million at auction. What makes this toy car so expensive? Well, first, it’s almost entirely built with carbon fiber, and then it’s lined with actual gold thread with solid-gold platinum and gold wheels. And if you look inside, you will see that it’s decked out in gemstones. NUTS.
