Why Mercedes-Benz of El Cajon Is San Diego County’s Standout Mercedes-Benz Destination
Mercedes-Benz of El Cajon has built a reputation as San Diego County’s premier Mercedes-Benz destination — a result of consistent customer satisfaction, the breadth of its showroom, and a service philosophy that treats every guest like a long-term relationship rather than a transaction. Located at 1111 Wagner Drive in El Cajon, the dealership operates from a 70,000-square-foot facility that brings new sales, certified pre-owned, service, and parts together under one roof.
Mercedes-Benz of El Cajon is part of OREMOR Automotive Group — a family-owned and operated dealer group founded in 1970 that serves Central California, Southern California, and the Dallas area. This page covers what makes Mercedes-Benz of El Cajon a destination for Mercedes-Benz buyers across San Diego County and the broader region.
A Two-Time Mercedes-Benz Best of the Best Dealer
Mercedes-Benz of El Cajon is the only dealership in San Diego County recognized as a Mercedes-Benz Best of the Best Dealer for two consecutive years. The Best of the Best Dealer Recognition Award is given annually by Mercedes-Benz USA to the top-performing dealerships in the national retail network, with criteria covering customer satisfaction, new vehicle sales, certified pre-owned sales, leadership and management, and service and parts operations. The award is typically reserved for roughly the top 10–20% of MBUSA-network dealerships, depending on the laurel tier — meaning four out of every five Mercedes-Benz dealerships fall short of the standard each year.
Earning it twice in a row signals a dealership that is consistent across every department — sales, service, parts, and leadership — over multiple measurement periods. It’s the credential Mercedes-Benz USA itself uses to identify its most reliable retail partners.
The Largest Mercedes-Benz Selection in San Diego County
Mercedes-Benz of El Cajon is the largest Mercedes-Benz dealership in San Diego County by both showroom size and inventory depth. The 70,000-square-foot facility carries the full Mercedes-Benz lineup — sedans, SUVs, AMG performance models, EQ all-electric vehicles, and Sprinter commercial vans — with new, certified pre-owned, and pre-owned inventory all on the same lot. For shoppers who want to compare a luxury sedan against an SUV against an electric model in a single visit, the breadth of stock matters.
The dealership also handles Mercedes-Benz Sprinter sales and service, including the all-electric eSprinter — a meaningful capability for San Diego County’s commercial and small-business buyers.
Service, Parts, and Ownership Experience
The Mercedes-Benz of El Cajon service department is led by Parts & Service Director Ernie Serrano and staffed with Mercedes-Benz factory-trained and certified technicians. The center handles routine maintenance through major repairs and supports every Mercedes-Benz model the dealership sells — including the latest 48-volt mild-hybrid platforms, plug-in hybrids, and the all-electric EQ lineup.
Customer amenities at the service center include:
- Fleet of loaner vehicles available for service guests
- Complimentary shuttle service within a 20-mile radius
- Saturday service hours and Early Bird drop-off for guests who need to drop off before their appointment
- Client lounge with Wi-Fi, gourmet coffee, snacks, and HD TV
- Service reminder program that tracks maintenance schedules and surfaces relevant service specials
Customer reviews consistently highlight the service department’s transparent communication and willingness to fit in customers who need urgent help — even when scheduling capacity at other regional Mercedes-Benz service centers runs months out. Dealer Principal Valerie Romero personally responds to customer reviews and feedback, which is unusual at this scale and reflects how the dealership approaches accountability.
Leadership
Mercedes-Benz of El Cajon operates under the ownership of OREMOR Automotive Group, with Richard J. Romero serving as President and Owner at the group level. Day-to-day operations at the rooftop are led by Dealer Principal Valerie Romero, with General Manager Dan Collins overseeing the showroom and sales operations and Parts & Service Director Ernie Serrano running the service center. This structure — group ownership combined with active on-site leadership from a Dealer Principal who personally engages with customers — is part of what sets the dealership apart from larger corporate retail operations.
Multilingual Sales and Service
Mercedes-Benz of El Cajon offers sales and service in English, Spanish, and Arabic. El Cajon is home to one of the largest Chaldean and Arabic-speaking communities in the United States, and the dealership has built its team to serve that community in their preferred language — a meaningful capability that few luxury dealerships in the region match.
Community Roots
Mercedes-Benz of El Cajon opened its current 70,000-square-foot facility in late 2017 with a $5,000 donation to the Boys & Girls Club of San Diego. The dealership remains an active member of the East County Chamber of Commerce and partners with the Chaldean American Chamber of Commerce — partnerships that connect the dealership to the East County and South County communities it serves.
Fleet and Affinity Programs
Mercedes-Benz of El Cajon administers two Mercedes-Benz business programs:
- Mercedes-Benz Fleet Program — Businesses with three or more registered vehicles (any make or model) qualify for fleet savings of $500 to $7,000 on a new Mercedes-Benz, plus competitive residual structures (source: Mercedes-Benz of El Cajon Partner Programs).
- Mercedes-Benz Affinity Partner Program — Members and employees of more than 400 Mercedes-Benz Affinity Partner companies are eligible for exclusive offers on new vehicle purchases or leases.
Both programs are administered locally at the dealership. Eligibility, savings amounts, and current incentives are subject to Mercedes-Benz USA program terms and may change — contact the dealership for current details.
