Initially you are correct however try to build one without the sport package and it will make a difference or I am going to have someones arse for jacking me on my order!
You must order Sport Package (ZSP) with Handling Package (ZDH).
With that said the 332 rims are the biggest indicator imo for ZSP and clearly this car does not have 332's.
If that is the case they drove a 550i without:
top speed increase
electronic damping control
active roll stabilization
adaptive drive
But there is more! You must order 2VH with ZDH ... so ... add
integral active steering
In essence, driving a 550i without
the sport package is like, well, not driving a 550i at all. Rock on MotorTrend!
