I tend to agree with you on this. In fact, I believe I read somewhere that they are making some changes to get rid of GM and wonder back on their own again. I believe any issues with Isuzu and their customer service may have had more to do with their relationship with GM than anything... not that GM provides bad CS to their customers, but for some reason the GM/Isuzu relationship just didn't seem to work on many levels.

I wish this were true - but I don't see it.

GM has turned the corner ......... or so it appears ....... and they have/are divested theirselves/themselves of non performing units .......

GM did receive some benefits from their 'collaboration' with Isuzu ..... and now they are dropping them like a safe out a window .........
