In the realm of classic American muscle cars, few stories rival the journey of Jeff Williams and Jared Gastineau with their iconic 1969 Chevelle SS. What began as a serendipitous encounter outside a Chevrolet dealership in Delta, Colorado, evolved into a passion-fueled partnership and the birth of Mile High Muscle.

A Chance Encounter
It all started when Jeff Williams, a veteran of law enforcement and a lifelong enthusiast of classic Chevelles, found himself in need of help with his beloved 1969 Chevelle SS. Fate intervened when Jared Gastineau, a skilled technician at the local dealership, stepped in to offer his expertise. Little did they know, this chance meeting would set the stage for an incredible journey into automotive craftsmanship and performance.
