Since you didnt purchase Mtech kit with the car why not go an aftermarket body kit? Theres some conservative designs out there...sorta.

 

Ohhh btw speaking of conservatorism...i dunno for what reason i find almost all aftermarket body kits a bit "ricey" (don't wana offend anyone with this...i dunno how else to say it, but you know what i mean) except maybe hamann. Alpina also is quite concervative if i recall. All the other brands just makes the e60 look like a cheap street racer.

 

If I do it, I want to do it right. The car is really a work of art IMO. I want to keep it as factory as I can.
