Having completed a few tutorials that have mainly focused on natural objects (such as the dragon head tuts). I've been modeling using NURBS cylinders and pulling and tweeking the hulls and vertex's, which has worked really well so far.

I've now started making more man made objects such as planes, automobiles and boats.

Should I still be using a basic NURBS cylinder, or should I be going directly for a poly or sub div? cylinder, sphere, or cube?

I'm just wondering what basic shape types the SM members here use to create these more man made objects?
