What's a good way to disable Bricklin

["K M" <symbiotic@hotmail.com>]

I just lost my garage here in San Francisco (right in time for the rainy 
season) and I am parking the car on the street with a cover. The 
"auto-disable" feature that seemed to come standard in Bricklins now 
can't be relied on (in other words, the whole car is finally reliable).  
By now I have enough time and energy invested in the car that I really 
don't want it to get stolen.  I have been popping the coil wire, but am 
wondering whether there is a better or easier way to disable the car.
