    WELCOME TO CHEN AND ASHLEY AUTO GROUP

    C and A Auto Group, A.K.A. “The Diesel Source” is the East Bay Area’s leader in the best years of diesel trucks on the market. We specialize in 5.9L Cummins, LBZ duramax’s and 7.3 Fords, the best years of each American made brand on the market which wont leave you stranded with countless issues and years of financial headaches. We put our trucks through the ringer using THREE different independent sources to do pre purchase inspections on our rigs. Left Coast Diesel in Concord is responsible for the mechanical side and safety inspections that ensure the truck will be sound for years including Oil Changes, Fuel Filters, Trans Services, Battery and/or Battery terminal services, checking all mechanical functions and proper operating functions from A to Z.

    With the mechanics in line, driving 3/4 and 1 ton rigs on California roads makes for some sloppy front end parts. Les Schwab here in town goes through our brakes, wheels, tires, alignment, ball joints and tie rods, finishing the trucks off with our custom look, usually consisting of Fuel or Method off road wheels and 35s with a beefed up levelling kit to give the trucks our signature Diesel Source look.

    We take pride in the product we sell and can literally sell a customer a truck and say we have done EVERYTHING we can do to make sure its as healthy as can be for its next home.

    TRADE INS are always welcome and if we don’t have what you are looking for, we can always find it for you and put it through our process ensuring you get the rig of your dreams.

    As Always,
    Cheers!
