I am planning to utilize a SUV pack and I am working on the Tahoe.

I wanted it to look like this, with some of the emblems and the extras on it removed:

But in game, it looks like this:

Is there something that needs to be done in zmodeler to solve this?

The Tahoe Badge object should be attached to the door/boot. You can remove this by going into Polygon Mode  and selecting the poly's for that object. Make sure you have selected mode on and press delete on your keyboard. Make sure you have no other polygon's selected when you delete what you need.

I managed to remove the Tahoe badge as well as the rooftop parts. The only challenge now is the removal of the items circled in black:

How did you remove the emblem???

I highly suggest using Perspective view, and using Selected Mode.

Perspective mode is like the 3D view, except you can see the polygon lines. When there is no Modify tool selected, you can rotate around the 3D car and select the parts you want too delete very easy.
