Bad export

[nigec]

I downloaded the Pearce 1931 model as lwo
http://www.dmi-3d.net/modelscar10.html
First thumbnail on that page
It imports into W3D no problem but fails totally to export as obj, Wings just freezes totally, I left it 10 minutes and it never recovered.
Exporting as 3ds, only a small section exports and you can not re import back into Wings (as 3ds)
This is the error:
