rare

So I was looking on Autotrader and I found this W203 C-Class Avantgarde in Orion Blue of which from what I have seen is very rare. I'm just wondering if it is possible to upgrade the supercharger that is in that engine to try and get out 200 BHP out of the motor?

Hey there I'm new to all of this stuff so sorry if something similar has been posted. I recently came into ownership of an E320 convertible and have been told it is quite rare. It has sportline badges but there is nothing to suggest this through the paperwork. I have been told it is quite rare...
