Nineteen89,
Paranoia will destroy 'ya. I find that if I treat my car like any other car and not a piece of jewelry that things will be fine. You can park in the back 40 of a parking lot and someone will always park next to you. I park right in the thick of the lot and nothing has happened yet. I can tell you that if you park in the middle of the space that a Boxster is small enough that there's allot of space for the other cars. Speaking of, park next to nice cars and not hoopties.
Those owners will appreciate the Porsche and might leave you money under the wiper just for the honor.
