[Edit] The renders are all under 3 mins (unless i add ray trace shadows)
The last render that i will post took me about 20+ mins to render. Shadows+Antialiasing Medium+50,000+ polys

The toyo tire that i am using...You might notice that theirs has less tread than mine. But i don't feel like redoing the whole thing again.

This is the wheel all patched up.

And this is the 350Z with the wheels.

I haven't forgot about this car :) I have added color and Specularity for my own personal reference to see any unsightly bulging.

I have added side mirror, the line on the side that extrudes out, and the indent in the bumper where the Logo of the Z or Nissan will go. Oh and also the Top layer of the Tail Light.

Render #2

Render #3

And the Last Render....Should i lower the car onto the wheels????

Well, this looks like its coming along nicely. There are still gaps in your mesh but you probably realise that without Captain Obvious having to point it out for you!

yes lower it a litle bit ! it looks awesome !

Thanx guys! Yea i'll try to fix the gaps by the next render.

oh...use a double sided material for the body so the shadow will be in one piece
