Broken Geometry on Import to Blender

[brektel]

Hi! I am trying to convert this car, the FSO Syrena Sport, to NFS Most Wanted (2005). The model looks perfect when its GEOMETRY file is opened in CarToolKit (CTK) and exported as an OBJ from CTK. However, as soon as I import it to Blender to work on changing the names of its parts, the car's geometry breaks (the headlights, the windows, and most notably, the trunk).

Does any body have any idea how to fix this? Would appreciate some advice.

I have attached the images showing how the car looks in CTK and Blender.
