There are 2 schools of thought on how to break in a new car. One is the one
outlined in the owner's manual, and the other is that a new car should be
driven hard to loosen it up, because breaking in a new car is like training
a new dog. A "looser" engine will perform better, rev more freely, and get
better fuel mileage at the expense at slightly higher oil consusmption as
the engine passes 150,000 miles than a "tighter" engine.

In my previous job, I was fortunate enough to get a brand new car every 3 or
4 months, plus, when new models were introduced we generally drove them for
a week or so to become familiar with them. When you work for an automaker,
your friends, acquaintances, and relatives all want you to get them
tremendous deals on a factory demo, and my friends and relatives who
purchased my factory demos did not enccounter any problems with them. One
friend keeps his cars to 300,000 miles, and he did not have problems with
them.
