Where did I indicate it was something to be proud of? I didn't, I said that many people do it and drive their cars perfectly happily, so the idea that this car would be instant scrap because the DPF is gutted is nonsensical.
Making false equivalencies that driving a diesel car with DPF gutted is somehow comparable to dumping used oil in a river shows just how moronic/one-eyed your viewpoint is.
Again, I'm not arguing for the morality of driving a car without a DPF, I'm just stating that if this particular car has its DPF gutted, it will most likely pass MOT fine and in all probability, it will drive better, and be more reliable than a comparable car with its DPF intact.
