i dont want to saturate your brain with lots of different (and some times contradictory) advice from lots of different people, and all the advice seems good so far, but here's my 2 penneth for a rookie
camera set up:
jpeg large fine
if it has colour settings then put it on something like landscape and max sharpness
ISO 100 if its reasonably sunny.. if its overcast then ISO 400, raining then even higher.
AF AI Servo
Auto White Balance
Drive mode - whatever the fastest burst mode is
centre weighted metered exposure
use centre focus point
(these settings are all for moving cars by the way, you probably already know the settings for badge shots
)
If you can see the wheels on the car:
Tv mode 1/320 shutter speed (slowing it down as you get used to it.. even as far down as 1/60 or slower)
If you cant see the wheels on the car:
Av mode set to the widest aperture possible
That's a good setup for a beginner. You'll get some good shots, but if you want to get really really good shots then there's a lot more to it.
