Question on "Break-In"
My brother delivered my new 2001 S4 to me from out-of-state with about 1200 miles (around 200 city miles and 1000 highway miles, varying speed/rpm). My question is should I now consider the car "broken-in" or should I go through additionl "break-in"? If so, what would you recommend?
Thanks,
Thanks,

Actually: the number of times the engine and ancilliary parts have been "heat cycled", is also very
relevant.
You have various types of metal in your engine, from cast iron, to aluminum (in various alloys). Break in is not solely a factor of friction. It is also the mating of parts in various states of "thermal variance" Since different metals have different rates of thermal expansion; Heat cycling your engine/drivetrain several times is also very wise.
If the car 1000 miles on the highway, and that was done in the trip to deliver it to you; I would take a week, and put a few more "cycles" into everything.
IMHO
