I'd pick a different car to model than the new Audi vehicles, the front grill area is especially difficult, the sides are very do-able for practicing techniques on surface structure and flow though ... Good luck with whatever you decide to model, there are some super MoI users on here that will help where-ever they can if you get stuck :)

After careful consideration I'll stick to using MoI for what it does best, making kick ass complicated parts that would otherwise take forever and a day to do with poly modeling. It took me about 9 hours in total to poly model a brake caliper. I'm quite good with Blender so I could combine the two, poly modeling for the body and then use MoI for the wheels, brakes, chassis, suspension etc etc :)
