looking at the summit sticker i got inspired to make this.. i was thinking of putting one in each rear 1/4 window in matching green vinyl. if enough people like it maybe we could find a vinyl cutter to do a group purchase
IMO those only work when you go to car shows where people have respect for one anothers property! If you are just going to use it for general purpose it will just egg some A-hole on to mess with your ride.
It seems alot like the alarms that talk. I had a friend with the talking Viper and people would mess with it just for kicks. He finally took it off because it drew too much attention. I would just park far away from others when possible, and be careful. Its the best you can do in todays society.
