Things have changed. Don't baby the motor, but don't hangout at redline, either. Even metals learn to adjust, but if you baby the motor and THEN try to "have fun" they'll have a harder time settling in.
You want to work out as much issues that could be had with the car as possible. Drive it like you normally would. I did with my WRX and got the seat-warmer switch and battery replaced under warranty just before the car reached 34.5k miles.
