Hello, as many of you know, the LACMTA has a giant collection of NABI 45C's and about 20 40C LFW's, which are made of composite material. However, NABI wasn't LACMTA's first compobus option, it was Northrop Grumman. I posted this on the Los Angeles MTA thread already, but I think posting this here was a good idea too. Only a small batch was made but Imagine if this was everywhere today...
