Honestly, if you're concerned about theft, there are mobile car alarms which are motion sensitive. Another thought would be to just remove the rotor (if there is one) and/or primary coil wire.

As has been mentioned, a stick is a millennial anti-theft device (LOL), but doesn't help those of us who drive automatics by choice and not by necessity. :-D

I have a convertible, and I have always felt that slashing a top to break in is akin to horse stealing, but it happens all the time. For us, aside from stealing the whole car, it's the damage which may be done by the would-be thief trying to break into the car which can be more costly and perhaps not as well covered by insurance than a total theft.

The Club is great, but cutting a steering wheel is a simple workaround with the right tools, ruining what might have been an expensive wheel in the process.

So, assume that a determined thief will get into the car one way or another, so look to do things to either make noise or disable the vehicle after the break-in. As has also been mentioned, a flatbed is kind of hard to thwart, but a combination of things (layers) should help even the odds.
