Why did you call it 'Marica'?
Cause of my best ex-friend.
This is very cool. I have to ask though, is this based on Erik's work? If so then you should credit him If not, then good work for building vehicles in POSTAL 2 from scratch.
No, it's not. He is already in credit, for his help with physics mp smooth =)
Marica is an old mod, http://www.postalsite.info/news.php?readmore=395#.UQYemme1wcw (the first beta test version)
