I looked at a few images of the 2006 Chevy Tahoe...like most vehicles, there are clearly defined individual pieces that you could model separately. The doors, fenders, headlights, grill, tail lights, door handles, bumpers, windshield and windows (along with the wheels, of course) could all be modeled separately and then put together (either as a single model or using an Action in a Choreography depending on how detailed you want to go). Just my two cents.
