BMW Z4 (E85)
I was working in this car one week, I first made it in BI Freestyle and after converted to Cycles.
It also have a simple Rig, of course it doesnt have suspention but you can move it and the wheels will also move, and have a simple direction.
It's good an envious toplogy flow :D I'm never able to do that when I'm modeling cars :P
Looks ok. Note the line of shape of the vehicle to a better, more accurate representation to obtain. In your interieur have you activated a the mirror, remove the passenger speedometer housing. Keep it up :-)
WOW!!!
