I am the third owner of my 2000 Ironman. To my surprise, I was recently informed upon my 60K service at Isuzu that I happened to have a 60k warranty on the whole drive train. I had no idea. Instead of charging me $630 for the service to be done, it was only $450 because of the warranty.
And to top it off, I picked my VX up from Isuzu yesterday, with a new tranny I never thought I needed. A $4000 gift. I have 58k miles on it. That was my reward for being anal and getting my 60k service at 58k
From Unimog to VX - a serious change in velocity - a small sacrifice in voracity.
