I'm looking into getting a certain 2008 C63 from a private seller within the next week. He says that the car has both the p1 and p2 packages. I've tried to search everywhere, but can't seem to find out what exactly was included in those packages. He says he also has the renntech ecu flash and the resonators removed which gives it some extra sound and 520 hp.

my main questions:

1. what exactly does the p1 and p2 packages include?
2. how do i know for sure if he has the ecu flash? would i just ask him for a receipt for the labor or what?

thanks guys.

any help please?

If you know a dealer, get a build list on the car. It will show every option, original MSRP, and in service date. I'd ask for a receipt for the ECU flash in case you ever need it reflashed or have issues with it. You can look under the car to see if the resonators have been replaced by a an X or H pipe.

Correct me if I am wrong...P1 was standard. P2 included, I think it was Xenon lights and adaptive lighting etc.
