I totally agree...it depends on the scenario. If it's Arctic, you don't wanna use a Swampskier or RAM. On the other hand, in the desert you don't want the Rockslide ot the Battle Bear.

I typically enjoy using jeeps, humvees or the like. Small, fast light vehicles that elite forces are known for, and occasionanlly some light armour and helicopters. What I tend to shy away from are the LARGE vehicles and Airplanes. The Large vehicles need huge spaces and wide shots, which land around here is at a premium and the odds are, photographing large vehicles will tend to catch real world objects in the background and be a photoshopping nightmare! And Airplanes...well, unlike some people around here (Sonneilon comes to mind) I can't do "in flight" shot for beans! I also shy away from boats and water vehicles. I don't like getting my Joes wet.
