I appreciate ya'lls' comments.
As i said, i'am completly new to this... i started with poly modeling from blue-prints (read many tutorials - not only from maya...). at about this stage (25.5.04)
i started experimenting with sub-d & converted poly to subdiv + messed up my poly-model file. ( :x ) So i was forced to continue in sub-div for a day. Then i converted my subd model back to poly and started cleaning polys (the convert left too smooth mesh to edit, so i started to manualy delete edges and build new straight ones). It took me about 3 days just for the hood... (thank god for auto incremental save function - i use it all the time now

).
Now it's poly only... Nurbs is a little bit hard for me right now, but i hope to learn it quick ... I made some parts of car in nurbs, but converted them in poly (steering wheel, car seats, windscreen).
thanks again for your comments.
p.s. the question still stands: how do you make nice borders between chasis parts (doors, hood, ....)? Do you use bevel? Scale down the door to make space?
Currently i have my chasis borders cut - but aligned (**0 offset) and i don't wont to mess my model up with ugly borders.
oh... i'am storing some renders on

(mostly tests... so don't expect anything...)
and you can see my progress from day 1 on

(screen-shoots as i'am posting my learning progress on some other forum). Will keep you updated!
