What Am I? Found on the 405

Welcome to another edition of DT’s cure for the Monday morning blues — What Am I? We
take a random picture of a car and you get to guess what it is.  Today’s feature is something I spotted on the freeway this weekend and had the wife snap a few cell phone pics. 

I really wish I could have gotten a better picture of the rear, because from behind this thing looked like space ship cruising north on the 405 in Orange County.  I’ve seen a few custom cars in my day, but this thing is really something else — but the question remains — what?

Apologies for the thumb in the picture, but the front windshield extends all the way down to the bumper.  What am I?
