My biggest problem with creating vehicles is generally the collision mesh. Not creating it, but merely that the textures are awkwardly glitched in-game.
I am not sure if it's even a texture issue, actually. But that is what it looks like.
Some pictures to show you what I mean.


These pictures are taken from a great distance, but the fact that it appears at all bothers me.
The meshes name in the program is always Collision-1, as naming it anything else(col-1, col0, collision0) seems to crash Blockland for me.
I export the models using Milkshape's Torque DTS Plus plugin, as I don't understand Blender enough to use it's exporter(I've heard it exports beautifully), and the Torque Game Engine DTS plugin always exports the model unflatshaded(the collision doesn't seem to have problems with this plugin if I recall, but again the unflatshaded thing happens).
I need some help to solve my problem, obviously. I don't know what "techniques" people may have used to do collision meshes, and searching doesn't seem to help.
