Owned my Vx since Dec of 05 and still had some warranty left. I had some drivetrain noises and the people in Corona said it was normal. I could not believe them so I drove to Douglas. The 3 Isuzu techs there are from old school and love the "real" Isuzu's. They spent alot of time on my Vx and figured out the problem. The new owner of the dealer is a Vx fan and always looks at the Vx's that come in. He personally looked me up and introduced himself. (Steve) He is always available! I highly recommend Douglas and my Vx will never go anywhere else... If you do take your car there, ask for Nicki and be sure to look up Steve.
Fyi = drivetrain noise was caused by bad front dif AND rear dif, both replaced. I figured about $8000 worth of warranty!
