Yes, I would buy a hybrid. In fact, I bought one less than two weeks ago. It is a Honda Civic Hybrid 2007 model.
Now, some people seem to have a slightly outdated view of modern hybrid technology. Current models do turn off the engine when stopped at a stoplight, they do not need to plugged in to charge, and the initial cost isn't terribly more than a regular internal combustion engine. As for miles per gallon, although it may vary from person to person, I get about 42+ miles per gallon overall and about 44+ on my most recent tank of gas. I should add that I haven't fully broken in the engine yet, so I do expect to gain a few more miles per gallon in the coming months and/or after my first oil change.
One thing I've noticed while driving a hybrid is that the real-time miles per gallon display has helped to make me a safer and more efficient driver. I can see, in real-time, what driving techniques give me the most savings and I am less inclined to speed while driving on the interstate. This seems to be common occurrence among Hybrid owners. However, do be careful about watching the road and not just the display.
While some people may scoff at the higher price of hybrids, it should be pointed out that if I were to buy a regular car, I'd probably have bought a comparably priced car or perhaps even a bit more expensive. As it is, I suppose I settled for a little bit less but since local gas prices are well over $3.00, I don't really regret it. Add in a federal tax credit of (I believe) $2,100 if you meet the deadline, and the initial cost seems even less offensive. I have yet to check if my state has any state tax incentives, but it wouldn't surprise me if they did. I have heard that California is allowing hybrid owners to use the HOV lanes. It wouldn't help me, but it seems like a nice incentive. Also in regard to money, it does seem that most hybrid sedans come equipped with a fairly high level of technology. I know that people say the Prius is like something out Star Trek, and that my Civic has amenities similar to the top of the line Civic EX line. That is one thing to consider when buying a hybrid, what kind of extra features do they include.
As gasoline prices are expected to rise to around $4.00 per gallon in the near future, I believe that I will come to appreciate my car's superb mileage even more. Strangely enough, the Prius hybrid gets even better mileage than my civic, but the civic fits my tastes better.
