Mark Christopher Service Dept
Genuine GM Service
Our service department is one of the finest in the Inland Empire. We've just completed a $500,000.00 renovation and addition. We are one of only a handful of dealerships capable of major motorhome repair and maintenance. Our service department delivers quality repairs at comparable rates.
  • All of our work is 100% guaranteed.
  • All of our technicians are GM certified.
  • We provide free local shuttle service.
  • We even have a rental car facility on site for your convenience.
