I posted here about this couple of years ago. I ended up with a chain in an inner tube and padlock like Steve says but I take it off before I drive AND I have a simple alarm with ignition kill and a motion sensor and remote. These alarms are like $50 and you can install them yourself, just like modern cars have with the four-way horn, blink the lights, chirp, etc. I have them in both my cars and the chain setups because I don't have a driveway and when I have them for the summer I have to park them on Boston streets. One thing I did do was to put two blue flashing alarm lights on the column cover rather than one, you can se the two flashing inside the car from a distance and I felt the blue to brighter than the red I have in my truck. I only have about 14" of chain so one wrap through the core/radiator support and a long hasp padlock it tightly up inside. To cut it, you'd have to cut the grille. Been working so far..
