please help me with this

 

You must first export the model as collada (.dae) in blender. If you want it to be a static object that is part of the map, it's fairly simple, and it's explained here:

If you want to make a movable object, like a prop, you need to learn how to jbeam. There should be everything you need on the wiki, but since it's a bit outdated you can look at official cars to see how it's done.
Making a car is the hardest of all. Basiclly it's the same as a prop, but there are a lot of other things to do and i don't think it's great to start.
