/\These. With an automatic you have no control over what happens or when. With a manual, you can increase the power available to you at any given time by shifting the gear ratios around, you can squeeze more life out of the transmission if you're good to it (not necessarily gentle
), and you can get better mileage by keeping your engine's RPMs in the most efficient ranges all the time. Plus it's just a lot more fun.
On a side note, I had a friend in high school who had a late-60's Mustang....with an automatic...heresy! I take solace in the fact that it was like that when she got it though. At least she wasn't the one who screwed it up.
