I was thinking that it might be good to add power locks & an alarm to my MK1 Jetta. Not to protect the car so much as to protect the contents. Occasionally I have a spare laptop with me, usually in the trunk, but sometimes in the car.
I'm thinking getting some of those antitheft plates for the door handle will be a start. But Loud sirens & blinking LEDs might help too. Any recommendations for brands, etc?
