Thx!
@ Autoque: no, it's aftermarket (Powersprint aka Supersprint). About 600 US-$ incl. installation.
@ AzNM: Dankeschön!
What does it mean "BMW is dragging its feet..." - is it for the motor (3.0sd / now: 35d)?. For me, it is a very favorable motor. Loads of torque, yet OK quite and "soft".
@kimg: Yep - that was a questions that wasn't answered to my satisfaction with xoutpost.com (or Motortalk.de in Germany) when I ordered the car. So I just had to try max. speed immediately after taking over. Everything above 220 km/h (135 mph) is a bit tiring, below it's absolutely OK.
