And a buddy of mine recently got a BMW Z3 coupe (with the special M3 motor?) that had a long break in as well...Jon Pike asks why don't modern cars require engine break-in. My 2003 MINI Cooper S had a stated break-in period of 1250 miles. The instructions were to not exceed 4500 r.p.m./95 m.p.h., and to not press hard on the brakes (if possible). So that is one manufacturer that still recommends a break-in interval. Dave De Rosier
