When I want my car to go nowhere I install a brand new Airtex Fuel Pump.
Just to be extra-sure that my car will not go too far, I'll throw in a non-OEM
Crankshaft Position Sensor, or one of the newest, latest radiators that are
now everywhere on the market.
Har, har. Just kidding! (...uh, sort of).
A Club will not make your car steal-proof. Nothing can. A Club will deter many,
if not most, joy riders and amateurs.
I do not keep anything valuable in my cars. I do not have a flashy stereo system or
GPS display or any other gizmo or tools that may whet anyone's appetite.
I use a Club on my steering wheel, and whenever I can, I will often park my car on a
well-lit, well-trafficked area ... near to a flashy BMW, or a shiny Honda.
