The Isuzu owners in the area where I live are pretty fortunate. A dealer that has a mechanic who has worked on Isuzu's for years including lots of VX's. If you have ever heard me before on the subject, you know I cant say enough good things about them. Many here on the forum have phoned them from other parts of the country for help in troubleshooting problems.
They get a big basket of goodies every christmas from me as a thanks for the superb care they give my VX.
