Why Our Customers Continue to Choose Diamond Chevrolet in San Bernadino The history of Diamond Chevrolet starts over 55 years ago when a man named Bill Bader purchased Jack Coyle Chevrolet located off 8th and F streets in San Bernardino and renamed it Crest Chevrolet. Bader relocated the dealership to where it sits now on 21st and I streets in 1975. Alam Khan of Diamond Motor Group purchased the store in 2019 and continued to operate as Diamond Chevrolet of San Bernardino. With a history deeply rooted in this city we are proud to continue to serve this great community and re-inspire the "Do It Today" motto.
