Your frustration and disappointment is fully understandable. I've owned Isuzus for 20 years and haven't ever had a major problem, but that doesn't mean failures don't happen. That's just another unfortunate by-product of mass production. And it's probably soured you to Isuzu.

Hopefully you'll make out well on the repairs and sucessfully complete the changes in your auto lineup that works best for your family. You'll be a part of the VX family as long as you want to be and your VX will find a new home that most certainly will appreciate the care you've given it and all the documentation as well.
