Personally I hope that the relative lackluster sales of the M5 is due to that buyers of the M3 and M5 expects a purer more focused drivers car that doesn't try so hard to be an uber comfortable compromise. That M buyers wants the equivalent of Porsche's GTS and GT3 cars. Ultimate and focused driver's cars with high revving NA engines with razor sharp throttle response, an agile and communicative chassi and superior steering feedback. Instead the new M5 is more like Porsche's Turbo cars with massive power and torque in a slightly softer more luxurious setup. To me the 550 is already doing this duty to a more appealing price tag. Maybe the M5 just isn't special enough in the lineup with the out of the box and highly tunable power of the 550, add to that the minimal exterior differences with the M-sport package. Maybe the lineup would have been more complete with a more traditional "purer" M car?
