i’ve tried that tut a bunch of times.
it never works no matter what… :\
Me too. I’ve done it twice.
Okay you have a few problems in the script and your objects names. You also have your van our of position.
First off, some of the python scripting should be indented. If you look at that little window underneath blender, it will show your mistakes.
Secondly, your wheels object names didn’t match the ones in the script.
Thirdly, the van’s center point was too high. Now you can see the wheels.
Now I redid it for you, but you still have a position the wheels according to where your van’s axils are. See attachment
Aw man, thanks! I thought the wheel names were right, lolz.
edit: still dont work and I did everything you said 
Oops, heres the right attachment. I already set up the wheels in the proper spot and adjusted them. I forgot to indent a couple other things in PowerTrain.py. There you go. Now it should work fine.

Thanks so much!!!
what did I do wrong exactly, for next time?
double post sorry
Just remember the outcomes after the if statement must be indented. If you see my other post, I attached an image of some of the python scripting. Where the arrows are, thats where it should be indented. If it is not indented, it wont work, and in the python command prompt you will see a message like - line35 in powertrain.py, expected indent not there - or something like that.
Also make sure you set your wheels in the correct position and give them the right radius via the carsetup.py.
If you need anything else, let me know
thanks a lot
