8: 1965 Ford Mustang – $80,000
The Mustang was the original pony car, and without it, we wouldn’t have the V8-powered sports cars that we have today. While the 1965 Mustang was one of the more affordable classic cars that you could get, its price has been skyrocketing. A clean, low mileage example will set you back around $80k (via Work & Money).

Considering the Mustang was not the most well-designed pony car at the time, this is shocking. Most classic car buyers would undoubtedly put a modern engine in the Mustang, and at this price, you can’t afford to do anything. The ’65 Mustang is becoming one of the most expensive classic cars on the market.
