markMark’s preference for Mercedes-Benz started in 1967 when his Dad bought his first new 250S. He first began working at gas stations and foreign auto repair shops before enlisting in the Navy where he worked as a jet mechanic.

Mark received his factory training while employed at the original El Cajon Mercedes which was located on Johnson Ave. and earned the title of “Master Technician.” He worked for a short time at Mercedes of San Diego before opening his own business closer to home.

Mark’s son Ryan Clifton works as service manager. Ryan has been with the business since 2004 but has enjoyed working with his Dad since before he could drive.
