Shelby GT 350 R
Carroll Shelby always had fun selling highly modified Mustang models to the public. That concept lived on with the Shelby GT 350 R. There were 30 of these high-performance Mustang models that went into production and each was signed by Shelby himself. The off-the-line performance of the GT 350 R was impressive to say the least (via Forbes).
The Shelby GT 350 R exhibited a powerful V8 engine which gave the car a fire-breathing amount of performance. The paint job and styling are unique for the period and made the car stand out compared to other Mustang models from the same period. There is no denying Shelby loved to tinker with the Mustang.
