OK, I see. Well, most of the cars we have now are not subsurfed at all. While I really like the nice rounded edges you got in that render, it may be pretty hard to get all that detail and still keep the poly count low. Most of our cars are only around 4000 faces or so.
If you do want to make a high poly count model, we have been thinking about adding some, that wouldn't be terrible...but I think we'll still want to give some users the option of switching back to low poly count models. Like me...my video card is slow
