Since you obviously model cars way better than you do characters, you should start learning how to do some lower poly car models. it's not hard to do and you could actually use them for something besides making your sigs -__-. Here's an example of a great low poly car model.
Wouldn't be too hard to model the same level of detail with a low polycount, will just take soem creative smoothing groups.
leave the moderating to the moderators who know what they are doing. for instance, Tek actually was very much on-topic, he was making a comment aimed toward a way you can improve how you work.
and i totally agree with him btw. there are many mods, and indeed game design companies out there, that need tallented vehicle modelers. but you cant really put a high res, meshsmoothed model into any game at the moment. so going low poly is the way forward.
