recent Road and Track Mag has these numbers:
M3 has it beat in every category, no contest. the 550 is no track car. But it is cheaper than an M, a fully loaded is about $68k in line with a E90 M3.
And we all know M5 has beaten the M3 in every category of performance as well except for skidpad and slalom.
If you want straight speed, buy a used M5, if you want a track day/ race inspired car, get the M3.
Not true, A fully loaded 550ix m sport goes for near 90k
