Brian Engcabo started Purity Automotive Detailing Specialists of Hawaii 30 years ago as a mobile service at a time when automotive detailing was not yet well-known among the general public. In those days, Brian had accounts with large companies like Alamo Rental Car and several used car dealerships who were more familiar with the art and science of detailing. In their business, used car lots understood the benefits of having someone revitalizing an aging automobiles so they could get a better price for it, while rental car agencies didn't have the workforce to properly maintain fleets of cars at the "new car" level.
