FYI.... Don at Isuzu was great except the dealership was sold and Don disapeared from the face of the earth....right in the middle of my oil consuption test! Last I heard from Don was that he was going to the new dealership but according to the owner of Sunset Isuzu he said he couldn't reach Don to get him lined up with the job. So I'm guessing that Isuzuwarehouse is probably defunct unless Don resurfaces. If I hear anything I'll keep you posted.
