Hey, no judgement there. I just would prefer my daily to be reliable and not roll coal.
Currently have a 3.0 tdi Audi that someone seems to have remapped while drunk, so it uh... rolls coal, but not the way you'd expect. It produces too much soot when driving quietly, and then after a long drive at steady speeds, when you let the engine live a little, it generates a cloud.
Being an Audi it's also not reliable like my Mercs have been, but it has ISOFIX which was my only requirement at the time. Also is a wagon.
