You also have to change Test_Car_01 in your model.cfg to the name of your p3d. So crtl f for Test_Car_01 and then replace it with your p3d name, in your case slm_s60. But like urbanized said you don't have the drivewheel defined either so create a selection with your steering wheel called drivewheel.
You aren't able to open binarized models, however if you want to see sample models go onto steam and download arma 3 samples and they have a sample car, house, boat and a few more. Hopefully this will help you out.
