there are people who believe it is better to break cars in that way...as cars do adapt to driving styles ect...theyre are more in depth reason that got to due to the metals in the engine (pistons ect) shaping.
Thats exactly how my dad broke in his porsche and it runs superstrong today after two year ownership. I'm believing the myth about breaking it in hard, though sadly i was to much of a pussy to break in the M like my dad!
