I bought this sound system ( exhoust ) http://www.a-alt-avgassystem.se/rostfrittsportavgassystembmwz4.htm
Custom made ripp of from sweeden ( close to my country.. 3 auer drive ) under a 1000 dollar ( eisenmann ripp copy )

Enny other things i can do to make it more ''cool''
 
Don't think there's much on the market to improve the performance of the 2.3i Sdrive
(unless you want to throw a great deal of money at it)
There's a few cosmetic improvements available if you shop around but there not to everyone's taste
 
I thought so.. yeye next time ! ,) i go for the biggest turbo engien i can find... gues it mait bee BMW Z1 ghost

I forgot to say that I work for a large bank where I am in charge of buying all the cars on behalf of the bank. The z1 will be relaunched (rumors from bmw)
 
On wikipedia i found this information
