Break it in!!! Don't be impatient. My brother got impatient with his 03 C320 Coupe, and blew out the cams and some of the valves within 600 miles!!!! They had to rebuild the engine, and now he has a noise in the engine that they say is normal that wasn't there before.

Edit. Also. My brother did drive it like he stole it, and thats why he blew out the cams and some of the valves!!!

Take it easy for a little while. Put some mileage on it, then open it up.

Personally if it were me, I'd drive it for 2000 miles, then gett he oil changed, then drive it for another 500, then change the oil once more, just to be safe.

Let my brothers lesson be a warning to you all. Take care of it, and it will take care of you. Abuse it like he did, and you'll be asking for lots of problems.
