The build quality of these compaired to the Stadler's is really shocking, I am on a Flirt for about 8/10 of my journeys these days but I still see far more 720s with issues on than the FLIRTS, for example, right now I'm sitting on a train with rattly panels, something banging near the bodysides and broken passenger information system with no screens.
We should not be trying to keep factories like Derby in business unless they are able to produce a quality and durable product and time after time again the stuff that is being built in Derby is far less durable than other places. If we save a factory just because it's British we're saying that essentially we care more about where a train is built than the quality of it.
