    Steering, Suspension and Tires

    The steering and suspension system on your vehicle is responsible for maintaining comfortable riding conditions, driving performance and safety. As each large tire on your car touches the road the actual contact patch tire of the tire is amazingly small.  Your 2 stocking feet together create a larger patch than an average tire does. Steering, suspension and tires keep those small patches on the highway at 70 MPH, even in the rain. It's good to have a seasoned professional inspect that system on occasion.

  • Engine Maintenance & Repair

    Automotive engine technology is advancing at an amazing pace. Vehicle fuel mileage is rising, throttle response and performance are very impressive. Vehicle emissions have become amazing low. We once measured carbon monoxide and hydrocarbon emissions at the tailpipe using a very expensive and sensitive machines. Most vehicles of today would likely  register a zero both reading on those machines. Today we are primarily concerned about reducing oxides of Nitrogen.
    The complex systems the vehicle manufacturer use to achieve low vehicle emissions are complex and advancing at an amazing rate. These are not bolt on systems. Advancing engine design, motor lubricants,  proper maintenance techniques and knowledge of the system are all and integral to keeping the engines running clean and performing well.
    Our technicians have computers at their tool boxes and subscriptions to a number of professional websites. They are able to stay abreast of advancing techniques for repair and maintenance of your European or Japanese automobile. We never wonder what oil specification is supposed to go into our clients vehicle, we find the appropriate specification to use.  We read about proper repair techniques and preventive maintenance.
    Our job is to better our clients vehicle condition, not harm it through ignorance.
