Reliability is paramount in MHO. My 2008 4/4 with Duratec motor has done 51k and only let me down once during that time, when a fractured plastic radiator leaked coolant. Now replaced with Mifsud one. Regular servicing/inspection is key.
Most trads are like creaking gates - they don't break, they just rattle, bump, squeek, leak and groan.
As for the M3, I have no first hand knowledge, but talk of cracked chassis and drivetrain issues is alarming.
Might a Moto-Guzi unit not have been a better power source. Two 1000cc pistons conspire to hammer V the thing appart.
