Looking at the speedo in that M3, looks like it's nudging 280km/h, or around 173mph.
Pretty impressive ,given the age the car is likely to be
I tend to drive mine at between 5+7.5k RPM on spirited runs,when fully warmed up , usually in 3rd + 4th gears, rather than 1st or 2nd,as I like to build the revs up through the gears.
They do sound very nice these engines...hence why my DSP stereo is usually redundant in the z, unless on motorways/dual carriageways.
The engine just sounds too good
