Porsche?
In my eyes boxer in twins has only one characteristic by which it's above alternatives. It allowed for car to look better, as in higher engines + current pedestrian safety regs in other engine layout cases would ask for supra-ish fat bulb up front, instead of low ferrari-wedge sleekness. On other accounts .. COG from engine alone is overrated, powercurve nothing special and many complain about torque dip for it, and pure performance/higher rpms imho are easier to design in inline engine imho, with potentially lower weight rest being same.
