Yeah what David said. I'm going to end this discussion with a super epic informative post lol
Manual - if you can drive one or learn how to drive one, and don't mind changing gears, get one. It's much more fun and offers a substantial amount of control compared to an auto. Pretty much the only choice if you're racing circuits, which I know most of you don't do but w/e (I race and I use an auto just because that's what I have) Maintenance isn't really that bad in comparison to autos, as autos need servicing too, they can sometimes be pretty complicated (you need special pumps to service it with, so no chance of DIY), and they have more parts to go wrong haha. They have a bunch of clutches and newer transmissions are all electronic which means they have a bunch of solenoids - one of mine broke and I had to fix it at 60,000 miles. Fortunately the Focus auto transmission is heaven to work on, fixed it up in the autozone parking lot for $500 and a few hours under the car, and that was a racing part!
So... instead of all that, with manuals you basically have 1 clutch and your master cylinder, and gear oil/trans fluid. If you are brave you can tackle repairing that.
Anyway I'm rambling, on to autos...
If you hate shifting or live in an area with bad traffic, go for it. Also useful if you plan on doing one of the following in the car while driving:
Talking on a cell phone
Eating and drinking
Eating and drinking and talking on the cellphone
Playing Game Boy
Racing your 6-second quarter mile car
Or bracket racing in general
A good compromise is a shiftronic, sport shift, whatever you want to call it auto-manual hybrid. If you don't mind a harsh ride you can get one and tune the transmission parameters in the ECU and change out the valve body to something a little stronger and shift faster than you can blink. Pretty fun, but offers less feel and control than an actual clutch. Some of them use paddle shifters, which is good because you can keep both hands on the wheel in situations where you need that. I'd say get one of these if you worry about heavy traffic and aren't concerned much about how sporty your daily drive is, but would like to have fun every once in a while.
