When I test drove the M3 for the first time, the sales rep was saying the car really doesn't need a break-in. Maybe a few hundred miles to get seals and components used to temp changes, but otherwise just floor it to red line.
Then, I took it out a second time for a test drive, and this sale rep was telling me to baby the car till 1,200mi. Then, something like keep the revs down until 4k mi or something.
I'm doing ED March 14. I plan to drive from Munich, to Vienna, down to southern Austria, and then up to Frankfurt. I figure I might get 700mi on the car or so. I will gradually push the car harder and harder during that period. While in Frankfurt, I'm going to make my way to the Nurburgring and drive it like I stole it.
I'm leasing the car, so I'm not overly worried about long-term wear. However, I am interested in hearing from owners who've had the cars for a couple years and didn't follow the 1,200mi break-in recommendation. Any probs? Thanks!
