Well, the wheel/tyre upgrade at least gave you 1" bigger wheels and 1 cm wider tyres.

The black pack, which appears to me to be some black paint instead of silver paint on some trim parts was a 4700€ option in Germany. There, Mr. Marketing earned his salary! 3949.58€ straight profit and the tax man got an extra 750,42€! It was a strangely popular option, often on white cars, which really need the silver highlights not to look flat and a bit boring.

Edit: Maybe it was not quite that bad, actually. It does include 20" wheels and some of the aero kit from the speed pack..

 

Well, I changed out my Sentas for the XJ Kasugas. To me the stance is much better!
