8. 1965 Shelby GT350 R: $990,000
As you may already know, Shelby started building Mustangs in 1965 as fire-breathing machines. They brought Ford some much-needed recognition and performance credentials. But, these cars were responsible for racing success. There were 34 “R” models they produced only in 1965. Ford sold them to privateers and racing teams all over America.
Those cars were not street legal and were purely for racing purposes – something that they did extremely well. The GT350 R had numerous modifications and was lighter, faster and sharper than the regular GT350.
Each example had numerous wins under its belt. In fact, every R model is an extremely valuable piece of Mustang and racing history. They rarely come up for sale but when they do, they achieve astronomical prices. That was the case in 2012 when a highly original GT350 R sold for almost $1 million. This car had only 4,900 miles on the clock, and the original transmission and engine.
All its important parts were well-known among Mustang aficionados. They raced it extensively but eventually put it into storage. This helped preserve its original condition, which affected the price.
