Our Team

Our History

Sierra Autocars is a member of the Sierra Family of Dealerships, selling and servicing Honda, Chevrolet and Subaru.

Sierra is a family-owned dealership with roots in the Auto industry going back 100 years and four generations in Southern California.  Paul G. Hoffman went from selling Studebakers door to door to owning his own dealership on Figueroa Street in Downtown Los Angeles to being the President of Studebaker.  His son Lathrop purchased the store which remained open until Studebaker ceased manufacturing. 

After a brief time in ceramic tile manufacturing, Lathrop purchased Sierra Volkswagen on Sierra Avenue in Fontana.  In 1974, he moved to Monrovia where Sierra Autocars (Honda, Chevy, Subaru) currently reside.  Peter, along with his sister Liz (Lathrop’s children), his nephew Mike, and daughter Leah carry on the family tradition of Sierra.  

Our Mission, Our Vision, Our Values

Our Leadership

Our Philosophy

Sierra lives by the mission statement that we see each guest and employee as a member of one family.  We are committed to a transparent, information rich purchase or service experience for all of our guests.  We recognize that purchasing and maintaining a vehicle is often a difficult balance between utility, economy, budget, and passion.  We strive to provide the high-integrity low-pressure experience that will help you make the right decision for you. 

Whether buying a part, having your vehicle serviced, or purchasing / leasing a new vehicle we are here to make you happy.  In the 1970s, when the US got its first Panda from China Sierra adopted the Panda as its mascot. The panda is a representation of friendship and goodwill.  Lathrop Hoffman believed that the Panda mascot would bring joy to people as you cannot help but smile when you see one.
