In the Mercedes's "In the Driver's Seat" book it says
-Drive your vehicle during the first 1,500km (1,000 miles) at varying but moderate vehicle and engine speeds
-During this period avoid heavy loads (full throttle driving) and excessive engine speeds (no more then 2/3 of maximum in each gear"
-Avoid accelerating by kickdown
-do not attempt to the slow the vehicle down by shifting to a lower gear using the gear selector lever
-select gear ranges 3, 2, or 1 only when driving at moderate speeds (for hill driving)
After 1,500 km (1000 miles) you may gradually increase vehicle and engine speeds to permissible maximum

The more important parameter is engine oil and water temperature before you hammer it. Just be aware that the oil temperature and therefore some internal parts take a longer time then the water to come up to operating temperature. The same applies to the transmission, differential etc.
If you are really serious you can bed in the brake pads but for a street car this is really not needed.
Engine and car break in is probably the fourth in old wives tales right behind sex, fishing and golf.

i followed the procedure until 600 miles. sort of. i mean. if you just don't hammer it and take it above 5k rpm and just sort of ease the engine in you'll be fine. my engine is still awesome. but uh, i've had a lot of electrical problems and stuff, which sucks. hopefully you won't have any problems.

I have for all of my cars just kept it easy for the first 1K or so. No quick fast acceleration. I have a friend who builds race engines for bikes and cars and there is a reason why they replace the pistons, seals, heads and tranny for each race or run. Sort of the same on our cars, but not to that extreme. The initial wear of the cams, pistons and rings will determine the longevity of the engine itself. I have also on all cars changed oil early on the first change.
