1969 Chevrolet Camaro ZL1

• Muscle cars were made to be bought at a cheap price; however, some of the most popular models from the '60s and '70s have become classics with their values skyrocketing. The Chevrolet Camaro ZL1 from 1969 reached the price of $715,000 at Worldwide Houston in 2015. The ZL1 model rarely comes up for sale, and if it does, the price doesn't go over $100,000; however, this one stunned the world as no one expected it to reach this figure. Nevertheless, it became one of the most expensive Chevrolet muscle cars ever sold at auction.
