Back in 2003, when I purchased new a Sentra SE-R, I broke it in leaving the dealer lot , bouncing off the rev limiter going down the street.
6 years and 103,000 miles later, I traded it, in perfect running condition.
I'd be more inclined to believe the 'break in period' with first hand experience and not what others say.
Now with the Z, i've given it more of a gentle approach, but I chalk that up to age...
