Were these wheels really offered as an option on Boxsters in 2003?

My first post here.

The owner of this car is telling me that the Turbo lightweight rims 18X9 (or 18X9.5 he's not sure) shown in these pictures were actually an option on this car.
He bought them seperately though.


I think they look too big on the car and are a liability in my decision to go for it:

Were they really offered that big for the Boxster?
