I hope you aren't presuming you are the only one to feel that way.
I think you should go back and read your second post in this thread. You specifically referred to the myth in question as being about VX's having engine problems. Skewing the numbers in favor of your opinion by including production numbers for all Isuzu models that use the 3.5 would do very little to nothing in helping to determine the root cause of the problem in the VX.
Admittedly, neither of us is probably capable of total objectivity at this point, so in conclusion, I'll just submit a last bit of knowledge recently reviewed with our old friend Webster.
myth (mith) n. [[< Gr mythos ]]: 1: a traditional story serving to explain some phenomenon, custom, etc. 2: mythology 3: any fictitious story, person, or thing. myth'i-cal adj.
Call me skeptical, but I don't think it would go over very well if you were to gather together all the VX owners who have experienced engine failures (whether they are considered premature or not), and tell them you think the problem is just imaginary.
