Car moving with mouse on x axis

Hello

I would like to make a similar effect with car movement found on that site:

http://www.berlinkebab.pl/

i assume that there will be something to do with “_x = _x+_xmouse” but how do i define the boundries and what about the wheel movement?
Or maybe it would be better to do this as a MC and if x of the mouse is less than x of MC then prevFrame, if its more then nextFrame ? Have no idea how to put it all together

Please help… !

Thanks in advance
