Download Unity3D and install the Pro Trial and purchase/download the fbx format of your car. Unity3D works well with that.
Open up a project in Unity such as UnitySandbox included with our SDK. Follow instructions to import the car model into your scene. From there you should be able to press the Play button and see the object stationary.
At this point you can look at the code and see if you can hook the car up in the same way we've Leap-enabled other objects in UnitySandbox.
If that particular car model is expensive, you may wish to find some other fbx file to try this process out with first.
