And about MoI and Car Design...
For sure MoI is not good for Car Design in terms of Concepting and forms research. Polygons is perfect tool for this. MoI may be suitable in modeling cars from already made concepts and blue prints. But it defenetly lucks of some essential tools for this work so it is not the best choise for car design.

Why I'm so against MoI in this situation is that I want people do not waste their time doing car design in MoI or any other "Organic" stuff. Their enthusiasm will finish one day and they will have to spend time to learn another app...And this is will be very hard. Because you will have to change your habits, minds, understanding of modeling etc... Personally for me it was very hard task. So this is how it was with me. So why people have to repeat somebody's mistakes?
MoI gives you a lot of inthusiasm with its simplicity but you will have to pay price for this - limited possibilities.
