I would definitely recommend getting a gamepad if you can. Certain games like FPS or RPG I like the keyboard, but for driving games the gamepad feels more natural with the analog sticks. I use a 3rd party Xbox 360 controller (MadCatz), it's pretty much identical to the Microsoft ones and only cost $25. Might not be worth it just to play MotorM4X, but if you have Steam and play a lot of other games you can get much more use out of it.
