I'm guessing that the H2's origins have a lot to do with the interior of the H1's. Being crammed up against a paper thin door with mounds of mechanical stuff roaring between you and your passengers and rain blowing in past the seals? And horking over $60,000-100,000 for the privilege? It's like nothing else! It's not the kind of car the executive type who can afford such a toy can get away with hauling anyone around in.
Although, I've got to say that seeing one getting stuck right smack in the middle of NW 23rd Avenue in Portland was hilarious. All the other drivers had to stop and squeeze over to let it through, but that didn't work when the bus had to get by. Pedestrians came to the rescue and redirected traffic to make room for the owner to get the thing out of everyone's way.
