I didn't make it!
Is there a way to save a map in mp because I have all these vehicles set up just the way I like it and I dont want to loose them when I exit
Your post is kind of vague. I'll assume you mean in Lugormod, on a modified map.
/mapents save, I think.
Makermod, I have no idea.
If you aren't using a mod like Lugor/Maker then as far as I know it's not possible.
