Just bought my first Porsche

There are silicone sprays for windows and the tracks, don't use WD. The window regulators are a real known flaw and stretch out and need to be replaced. If the windows don't drop properly when you put the top down is a clue that they have stretched.

The starter issue could be the ignition switch hanging up. Another know weakness for the Boxster.

Have fun and drive it hard.
