2. Shelby EXP500 Green Hornet: $1.8 Million
When talking about the most expensive Mustangs, it is essential to mention the Green Hornet, even though they never actually sold it. Still, the car received the highest bid of $1.8 million, but that wasn’t enough to buy it. For those who don’t know, the Green Hornet is another experimental Mustang from Shelby’s heyday.
Although it wasn’t the only one, the Green Hornet had the most innovative features. It had a 390 V8 Ford equipped with fuel injection. They also gave it unique disc brakes on all four wheels and an independent rear suspension. With this layout, the Green Hornet was a capable car that handled and stopped better than any other sports car on the market.
Unfortunately, the cost of producing those features was too high. So, Ford and Shelby decided to go with more conventional technology. Ford crushed most other prototypes; however, the Green Hornet managed to survive in the hands of an ex-Ford employee. He restored the car, so it is in perfect condition in the hands of the man who saved it from the crusher.
