I doubt that the other two DMUs meet FRA crashworthiness standards, which basically mandates that passenger trains used in the US be built like Sherman tanks. This is why Amtrak's Acela train weighs about twice as much as a comparable European high-speed train. High-speed rail in the US has no future until the FRA updates its standards, or creates new standards specifically for high-speed rail.
pretty sharp-looking, though. The only thing that would make them look better would be some pantographs and overhead wires.
