Hey, I'm new to the forum and just picked up my first 280z. Amazing car but I'm a bit worried for it since its parked outside most of the time. I was going to get a modern security system, but was unsure of how practical it would be to put a system into an older car (its a 1977). While looking at systems I found the Grant steering wheel quick release which seems to be pretty practical and would probably deter more people than the average security system. Do any of you have experience with either security method? Any suggestions? Also, I have an ignition cut off switch already hidden in the car as well as cylinder key locks for the doors.
