Just a question, but if you manage a multi-million dollar company, why do you need to be so concerned about how much you spend on gas??? Seems to me that you would have enough money that it really wouldn't matter.
Around here if you drive 60 on the highway, you will get run over by school busses (and everyone else). I'm sure I don't make as much money as you, but I bought the H3 NOT as an economy vehicle and I knew what I was getting into. I don't see taking the chance of causing an accident worth saving a couple bucks a month (which is about all we're talking about here). But it may be different where you live, so to each his own.
