Default boundary layer

Hi all! I'm trying to simulate the flow over a car in 2D. I'm using Tri elements for the mesh (run in Gambit). My doubt is that I don't know the convenience or not in using boundary layers to define the mesh in those regions closer to the car's surface. Can anybody give me advise about it and, in that case, the criterion to select the thicknes of that boundary layer?

Thanks all, again

Fer
