Body in a tunnel

I have a 3D car body in a tunnel which is already meshed in GAMBIT and ready for simulation. Now I don't know how I should simulate this model in Fluent. This car is travelling at a max speed of 100 km/hr.
I know my operations around Fluent but would appreciate if anybody could give me an idea on how to simulate this model.
Some people are saying that I should iterate starting with laminar velocities first (0.05 km/hr, 0.09 km/hr according to my Reynolds number) and then start with turbulent velocity increments (eg. 10 km/hr, 20 km/hr etc...). Some people are saying that I can start turbulence modelling right away with 100 km/hr. I am so confused on whom I have to trust.
Could anybody give me an advice on the proper way to run similations?
Also Could you please tell me what I should be studying in this simulation other than drag coefficients?
