I really don't want to labour a point, but the tightening up of laws was the reason that manufacturers were forced into fitting DPF's in the first place. I agree there are still older diesel engines chucking out contamination, but they had to start the process of cleaning up the circumstances somewhere.
I'd rather have a car perform properly than be lugged with constant DPF problems
Sadly, this seems to be a typical statement. The car WAS performing properly and cleanly, as designed. If you wish to take the "not in my backyard" stance, then perhaps a non diesel car with a different set of performance criteria, would have been a better choice for you.
I'm sorry but in my view, by taking the actions you have, you are just flouting all the hard work and design effort that has been undertaken to try and improve the situation overall.
