I've been thinking about this myself. I have 10 thousand rainy day dollars that I have kept for a while. Bonnie and I agreed that whatever we eventually do with it that we both had to be 100% on board. If even one of us disagreed in ANY way that we wouldn't do it. I haven't brought it up to her yet but I really beleive that if GM can rebound and when they do it could be a 'super ball' type rebound. And I'm talking about the whole 10 grand. It's been sitting idle not doing ANYTHING for us.
The bigger the risk the bigger the reward. I'd put my chances at pulling the trigger at about 15% right now meaning I probably won't do it but
I mentioned it in a thread the other night, can't remember which one but I'm with you, it could pay off.
