Bill might well drive a Model X and any number of other cars -- his daily was an armored mid-90's Lexus LS for many years -- but if there's a Porsche 959 parked at the south Kirkland Burgermaster, the odds are overwhelming that it belongs to Bill.

This because only 345 Porsche 959's were ever built, and none were eligible for import into the US. That is, until Bill made himself instrumental in the passage of the show and display importation exemption* so that he could buy one.
