Wow, Greywolf, Why don't you and I carpool? You practically have my exact same commute! The only difference is you're in FL and I'm up here in PA.
Your thread is interesting to me and my thinking is identical to yours. I've nixed the Civic (and the other smaller cars) as a possibility for noise and ride quality as I'm getting older and need the "full commuter sanity support package" of decent ride (wheel base) A/C, CD player and reasonably quiet driver's compartment.
I've been fantasizing about hybrids but just can't get over the feeling that they're not quite ready for prime time yet, plus the upfront cost premium and that "Sword of Damacles" problem regarding the battery pack.
Currently I'm driving a 1999 Ford Taurus w/V6 and it has been a good car, although not an excellent one and I think I can do better with either a Honda or Toyota next time. With 105,000 on the Ford, "next time" is coming up. Interestingly, the Accord was high on my list the last time, but the Ford got the nod because it came standard with the V6 and there is a dealer in town. The Honda was a couple thousand more for the V6 and there's no dealer convenient to where I live. In retrospect, the Honda would have been the better purchase.
