Well Done memnon....hope you will enjoy it...and go easy for the first 2.000 kms.
I find that the Boost CD with the extra Hi-Fi speakers is quite good. Compared to the Hi-Fi of my BMW (E46, 325ti) is of the samel sound quality (or at least that is how I hear it!). I do not know about the standard Boost CD.
