Anyone have Hyundai Getz car model?
If not one has it on GrabCAD that can give you it then you may find the blue prints on http://www.the-blueprints.com/
That way you can model it your self if that is an option?
If not then you can put a request in on www.grabcad.com/requests
and maybe some one might be kind enough to model it for you but I know there will be a lot of work in that model for what you want... So there is one more option if you want that model bad enough....
You can pick a CAD engineer/designer from GrabCAD just go through there profiles as there is a number of great car modellers on here with so much experiance and skills - you could ask them to do the work for you if you pay for there time in creating what you want?
I hope you get it sorted one way or another.
